If you want to find new music, not just new releases but stuff that you haven't heard before, Pandora is the place to go. When you find a groove with a station you get a sensation similar to that of listening to your favorite local station. While there are limits for free members, they aren't crippling. I'm cheap but I would consider paying for it. Pandora deserves the money.
Best music discovery site I've ever used. Makes interesting suggestions. Wide range of music including rare material. Easy to use. Helpful support staff. For $36 a year no commercials. Cons: New music added slowly. Not comprehensive for genres and artists. Really need to subscribe to avoid commercials. Getting your rating info is cumbersome. No global don't play this artist setting.
Great way to find new music that you might never have thought of listening to before. Cons: More and more ads. Can't request specific songs, and it takes some time before Pandora fully learns and adjusts to your music tastes.
i love pandora! it takes the music i like and plays it along with other music i havent heard before but is similar! its so cool! Cons: You can only skip a few songs a day, and its got about a million ads
