Going very slightly OT, my main band has a one-member-veto system on any new song (though it's not like we have a formal constitution and that's written down somewhere ) but I never exercise my veto without first learning to play the song, no matter how unenthusiastic I am about it.
Some of the best basslines I've played have been in songs that I hated!
Plus I wouldn't want anyone to think I had vetoed a song just because I couldn't handle the bassline. No, the truth is that Rythm Stick is a rubbish song with a rubbish bassline. Ahem.
