Lightweight MP3 player with quick and easy playlists - Windows Freeware. yPlay is an MP3 player with multiple playlists and a clean interface. I find too many music players have tiny, ambiguous controls and overly complicated menu structures.

I'm only interested in how quickly I can find and play a particular track or set of favourite songs. yPlay has a filter built into the main screen - type in part of the MP3 title or artist and the list will only display matching tracks. Double-click the track you want, close the player to the system tray and forget about it. Free software from the author of the Hal Spacejock series.
