If you are, then I highly recommend AoL’s Winamp. It comes in a free version and a paid version, but even the free version is a quality product. The sound quality is heads and shoulders above others like Windows Media Player, and it also offers an extensive online radio service. If there’s a particular genre you’re looking for, chances are Winamp has it listed in its directory. It even cataloged an online Gregorian Chant station! About the only downside I can mention is that the free version of Winamp has some trouble playing MP4 video files. If you want to know more about Winamp in general, then I definitely recommend checking out their official website.
