well, I need to work on about 12 songs for this band I joined today (see my "yayyyyy!!!!" thread) I learned like 4 of them in under an hour, and the other guitarist already knows all the lead stuff, I just need to play the rhythm stuff, which for the type of music that it is, is three power chords..... other than that, I'm usually not learning any new songs when I pick up my guitar, it's usually writing licks that I always forget the next day.
