Media Player and Realplayer on the Web, though the interface with IE will cause the whole computer to put on blinders and not let me do anything else if it is having trouble connecting to the source. I'm not much of a Microsoft fan for most things but I've gotta admit those Windows Media files have a really nice sound quality to compression ratio, better than MP3 byte for byte. Of course, MP3 is far more universal so it won't disappear very soon.

For MP3s, I use the MusicMatch Jukebox that came with my Dell. I used to use WinAmp on my old `puter and I liked that too. They're all pretty much similar. I just wish I hadn't upgraded the MusicMatch software when it prompted me there was a free upgrade available. Now I have nag screens popping up when I shut it down.
