Yea, the continuous guitar solo ending! RockBand fans everywhere curse the dude who wrote this "poor-man's Freebird".
I have found if you are just wanting to pass any song and aren't that worried about hitting everything, concentrate on kick (orange) and snare (red). That should at least keep your meter level. Then, if that's boring, add in the high-hat (usually yellow) or ride (blue or green)... but if you feel the rhythm failing, go back to the kick and snare 'till you get back in the groove.
This, of course, blows any 5 star hopes or even a high percentage at the end. Plus it's not recommended if you are trying to get good. But it should get you to the end of most songs.
