I honestly will never get tired of new downloads, websites, and applications for digital music (especially free ones) because music is my constant companion to my all-day computer sessions and keeps me sane. Or somewhat sane.
Anyway, Songbeat is an application that lets you download or stream any previously played music from Seeqpod (and I assume, most other streaming-music hosting sites). For now, it's only available for Windows, but will be available for OS X "soon," so fingers are crossed. Enjoy, Windows users!
