This cool hack created at the Toronto Music Hack Day by Devin Sevilla from Rdio looks at what you are currently playing in Rdio (using the Rdio ‘now playing’ API) and then finds all the remixes of that song that have been posted to to Soundcloud. It is a fantastic idea and works great. I really had no idea how many remixes are posted to to Soundcloud. For instance, check out this orchestral version of Skrillex’s First of the Year.
A really cool hack. Check out Remixes on Soundcloud
