I've seen all too many music disc threads on AVS, on so called "quality" digital music discs. 
It's a son of a gun to figure out what/why the poster liked the disc that they are recommending!
And when I finally do do enough homework on a recommended disc, and buy a copy of it, it too often is a total piece of crud for one or more reasons.
So, I plan to edit/add discs to this 1st post as we go along; and here's what I want in this thread:
If you think that I've ID'd one of my recommendations incorrectly, post and let me know and if it makes sense I'll correct my 1st post assessment of it.
1. 1st and foremost, this is NOT the place to post any music BD disc recommendations! If you do, I will complain to the moderators about your out of line post!
<4/27/'09 edit: too bad I didn't think to add this to the title. If it proves to be an issue, I'll PM the moderators and ask for a title chanbe.>
2. Meaning that CD discs and SACD discs (2 channel or MultiChannel (MC, 3.0 to 5.0 to 5.1)) are the most reasonably priced and popular digital music discs.
While DVD-A MC disc quality is either similar or even "superior" to that of SACD, there are a lot fewer DVD-A discs out there (than SACD), but they are generally not too bad on price and I welcome any and all recommendations on them so long as they meet the other (following) requirements.
3. The overall Sound Quality (SQ) is good.
I mean if it's a popular Beatles piece but the SQ and/or disc mastering is/are questionable, kindly do not post it.
<4/27/'09 edit: I've currently got roughly 8 DVD-A discs, vs close to something like 200+ SACD discs. Best Beatles disc (mastering-wise is the dual disc "Love" offering. (CD and DVD-A discs, by Capitol?)>
4. Any genre is OK; pop, rock, jazz, classical, new age, folk, blues, etc.; just be *sure* that you put an ID of what you think it is.
5. The disc mastering is at a minimum decent; not this compressed crud that is all too often the case with popular big selling CD discs.
6. If only a few tracks on the disc are worthy, kindly say so and identify those tracks that you think are worthy.
7. <4/27/'09 edit>: In general, the best label for "inexpensive" MC 5.1 music has so far been Linn hybrid SACD discs.
OK, with that said, 1st a few examples (also included in the following main list), and then the main list (alphabetically by main performer, within a genre group).
Soft (?) Pop/Rock
Dire Straits, Brothers In Arms; entire disc; 20th anniversary SACD
Paul Simon, Hearts and Bones; entire disc; Japanese import CD
Jazz
Dave Brubeck Quartet; entire disc; SACD (5.0? For sure no LFE)
Classical
Beethoven 9th Symphony; SACD (mono?/Tahra); 1954 Furtwangler conducted live performance; a great performance and not for background listening; surprisingly good SQ from '54; final movement has top vocalists at the top of their form; of my two 9th symphonies the faster is 68 minutes, but Furtwangler nails it at 75 minutes.
Complete list:
CLASSICAL
6-22-'09: Bach, The complete Goldberg Variations '55/'81; 3 disc set; Sony Classical, Glenn Dould playing ('55/'81/comments) of the Bach Goldberg Variations.
Bach, The Well-Tempered Clavier I; CD; Glenn Gould on piano; Gould plays the notes in this striking individual way; worth buying even if you hate Sony; good mastering which minimizes Gould's humming in the background; excellent for background listening
Bach, The Well-Tempered Clavier I; CD; If you really hate Gould's playing of this, then try Richter on RCA Red Seal; excellent for background listening
Beethoven, 6th Symphony; hybrid SACD (L/R only); Munch/Boston Symphony/RCA Living Stereo; OK for background listening so long as you can repeat the 6th without going through the 5th which is also included on this disc; great L/R SQ from '55
Beethoven, 9th Symphony; hybrid SACD (mono?/Tahra); 1954 Furtwangler conducted live performance; a great performance; and not for background listening; surprisingly good SQ from '54; final movement has top vocalists at the top of their form; of my two 9th symphonies the faster is 68 minutes, but Furtwangler nails it at 75 minutes.
Haydn, 11 Piano Sonatas (opus 4,6,9,20,37,40,42,48,49,50,51,52, but of course that makes 12 (LOL, you have to keep a sense of humor
)), Brendel; CD; excellent for background; AFAIK this is available by either Philips or Decca, I own the Decca and it is much less expensive, AFAIK the recording is the same for both, adding only that the Decca mastering is as good as it gets with CD so why pay the extra money for Philips?
FEMALE VOCAL
Not always sure what ID to put these under, any suggestions appreciated.
Holly Cole; I Can See Clearly Now; a very short CD (11-to-12 min. total); expensive; unbelievably good
<4/27/'09 edit>: Eileen Farrell; Torch Songs; CD (57 min. total); RR 34CD
MIXED/SAMPLER DISCS
I was more than a little surprised to discover that I like many sampler discs, and they are in general well mastered.
Concord Jazz CD Sampler Volume 2; excellent for background: despite the "CD" in the title, this is in fact a 5.1 SACD (hybrid/with CD) with decent LFE
<5/02/'09 and 6/22/'09 edit>: Groove Note True Audiophile The Best of Groove Note; hybrid SACD sampler; odd title mix so search for either Best of Groove Note or GRV1036-3; odd mix on each layer choice: the CD and stereo SACD have 17 tracks totaling 77 min. 30 sec. which is one good reason to have this disc (i.e. commercial CD pressing that totals more than 74 minutes), whereas the 5.1 SACD music only has 7 tracks (36m/46s); both 2 channel and 5.1 can be used ok for background listening; roughly 50/50 mix of vocals and jazz/pop intrumentals.
<6/22/'09 edit >: Groove Note sampler #2 only has 2 MC tracks and is not further considered, given the high price that I paid for it).
<4/27/'09 edit>: Heads Up, Jazzin' Surround; hybrid SACD sampler
<4/27/'09 edit>: Heads Up, Sound & Vision SACD Sampler (hybrid); with/via Telarc
Linn Selektions; SACD 5.1; excellent for background; has LFE
Reference Jazz, Etc., First Sampling, CD; works as background; RR-S2CD (one CD), jazz and vocals
Windham Hill CD; excellent for background
1. The First Ten Years
2. Sanctuary/20 years of Windham Hill
3. A Quiet Revolution/30 years of Windham Hill
JAZZ
Dave Brubeck Quartet; Take Five; entire disc; SACD (5.0? For sure no LFE, and not hybrid meaning no CD layer); a classic; excellent SQ
Miles Davis; Kind of Blue; entire disc; SACD (5.0? Doesn't seem to have LFE, and not hybrid meaning no CD layer); a classic; excellent SQ
SOFT (?) POP/ROCK
Dire Straits, Brothers In Arms; entire disc; 20th anniversary hybrid SACD
<4/27/'09 edit>: Joni Mitchell; Both Side Now; Reprise (domestic USA?/Reprise) CD; primarily for track 12: "Both Sides Now" but the whole disc is decent and worth having (meaning that the rest of the disc, IMO, is nowhere up to the quality of track 12); most (but not all) of the tracks are HDCD encoded
Pink Floyd, The Dark Side of the Moon; hybrid SACD 5.1; a real ping pong MC fest, but still worth having
Paul Simon, Hearts and Bones; entire disc; Japanese import CD
<6/24/'09 edit>: Steely Dan, Gaucho (per ematcion in post#7), I have the DVD-Audio (and not the SACD) as well as a standard redbook CD; only listened to the stereo option that the DVD-Audio menu gives, so may add comments about the MC and/or CD sound when the weather cools off.
<4/27/'09 edit>: James Taylor, JT; hybrid SACD
Addendum:
1. 6-22-'09: 5.1 optimizer disc: Chesky, The Ultimate DVD Surround Sampler & 5.1 Set-Up Disc CHDVD221 (reasonable as a used disc at Amazon as most of these people don't know the diff between DVD-Video and DVD-Audio (hence the very mixed Amazon reviews))
Also happens to have the finest 8 tracks of 5.1 DVD-Audio *music* that I've yet come across in my admittedly limited experience with DVD-Audio discs.
2. 6-22-'09: THX optimizer disc (included free with many DVD movies). Convenient and fast. My suggestion is to buy the 1951 black and white American TV movie "The Day The Earth Stood Still"
3. 6-22-'09: added the Sony 3 CD set of Glenn Gould playing ('55/'81/comments) of the Bach Goldberg Variations.
