It indeed depends greatly on what music they like. I don't know if they're into it, but alot of Nirvana songs are pretty easy to play. The thread "easy songs to play" contains 4 Nirvana songs. They sound pretty cool without being too hard.
If they simply don't have roughly the same musical taste, you'd probably be wasting your time. There are however quite a few very "accessable" songs that most people seem to like and would like to play.
