Currently picking back up a side project I started a few months back called The Daily Drop (http://www.thedailydrop.co). It aggregates EDM songs from around the web into a single location with the usual playback/music controls.
Originally created it because I just wanted a way to not have to manually go to different sites, forums, and blogs looking for new stuff, so I automated it. I 'launched' it thinking others might find it useful. Pending an approval from Apple, a native iOS app should be out in the next few days or so.
