Well until the R.I.A.A. draw a line somewhere then I would question wether sharing any music is even close to illegal. I firmly believe it's what you do with the music you share...for example, I'm a DJ and use my music for promotional use. We don't make tons of money and the internet just happens to be the best place to find new hot music so you can go out and buy their CD knowing what your buying is good cuz you've listened to it already.
