As long as we're hearing from all sides I'll ask the instrumentalists a question. How many times through do you play a tune? Is there a standard or is it just as many as you feel? As a singer and accompianist I'm frustrated to hear a dozen repetitions of what seem to my ear the same tune. If I sang the same verse in a song twice it would be seen as a slip of the brain. If I repeated it ad nauseam the listeners would be assuming insanity.
And to echo an earlier comment about being willing to play half an hour of tunes but not being willing to listen to them, amen. This is similar to a lot of discordant modern choral music I've sung which is tricky enough singing to fully occupy my brain but which I couldn't stand to listen to.
