I'm in the same boat as everyone else... I know maybe 5-10 songs from start to finish and they're my favorite songs. But I mostly take the riffs and licks that I like and play around with them. I think that is vital in developing your own chops. I think if you just learn a ton of other peoples songs you lose the artistic part of playing the guitar. I hate jamming with people that only play other peoples songs... When you're jamming out and some guy starts play a solo that sounds a lot like "Pride and Joy" or something like that... it bugs me. Those type of people don't make good ARTISTS... they make good guitarists... but they don't know how to come up with a good rythym riff... or play a lead with a song. So I'm the same way... I have folder after folder of songs that I've maybe learned one or two riffs to.
