To Echo what bo3bber said above: I am in the reverse position. I put a good amount of effort into my bass releases, I don't have much will to get into guitar tabbing since my band duties rarely call for me to pick up a guitar. I don't mind adding Vocals or Proper Riff repeater sections; I think he is spot on when he says an approved-tiered (bronze, silver,gold) system would be great, so those who do release quality single tracks aren't left off the approved list completely.
