So the decision of one or the other is based not on the genre being "music", but the recording being 2.0.
You can use Movie or Music mode for any genre of content, in either 2 or 5.1-channels. Most newer movies work best with Movie mode. But there are examples of movies in 2.0 or 5.1 that work better with Music mode. These tend to be cases where the stereo is essentially mono, or the surrounds are either mono or highly correlated, and in a 7.1 system that would cause all the surround audio to come from the rear speakers only. It is usually nicer to have all 4 surrounds involved, and 5.1 Music mode does that.
One other question / topic . I want to experiment with height channels. I have all the hardware in place. However, my processor will make me give up the rear surrounds. Instead of giving them up, I was going to just put a splitter on the side surrounds and send the signal to the rears as well. This will free up the processor to give me heights. Potential pitfalls I can see are delay settings. Any comments on this approach?
The main problem you will encounter is not because you cannot time align the 4 surrounds to your listening position, but rather that you might not be able to time mis-align them sufficiently to avoid a dense comb filter effect. Depending on the speaker geometry, it might sound just fine to split the surrounds. If you rock fore/aft in your seat, while some wideband surround sound is present like rain or applause, and you detect an obvious comb filter effect--a strong shift in timber, it might prove annoying over time. Otherwise, you're good to go.
