Ages ago, I downloaded both WinAmp and MusicMatch and decided MusicMatch was the one for me. That was version 4.something. Now, MM's up to 6.x and it seems every new release eats up more system resources. And I haven't been able to depend on it to record to MP3 without losses (to the extent that I get about 50 seconds of music for every minute of recording). So, a couple weeks ago, I took another look at WinAmp and was well impressed. No, it won't record, so now I have to record to a wave file and encode to MP3 separately, but at least I'm getting the complete source. And WinAmp is very easy on system resources. And WinAmp has some neat addons, including skins (although I stuck with plain Sport Yellow the whole time I used MusicMatch).

For me, MusicMatch has just about outlived its usefulness.
