From wikipedia: “RCRD LBL is an exclusively-online record label that offers all of its music for free via Mp3 downloads, while generating 100% of its revenue through advertising and sponsorship. Developed and run by Downtown Records CEO Josh Deutsch and Engadget founder Peter Rojas.”
The site adds new songs every day for free, legal, download, very often from well known artists (e.g. recently from Wolfmother, The Sounds etc) as well as indie artists. You can download for example one of the best songs of 2007 (according to critics), Blitzen Trapper’s “Wild Mountain Nation“. Today, I added quite a few of their free songs on my “best free songs list” to save you the hunting for the best of the best.
Recently they also started offering for free Bloc Party’s “Signs” remix, which is a fantastic track, and way better than the original mix. So good, that the band will release the remix as single soon. Here’s the official video for the song, as good as the song. There are a few scenes in it though that are not safe for work, so be aware!
