Soundcloud Concept
I love SouncCloud. It's a tremendous service and community. Lately, I've been using SoundCloud iOS app a lot and as with everything, it can be better (but it still rocks!). Especially the playback flow.
I thought this could be improved by using context actions for every sound in the stream as well as using playback planel for easy control. And when I was in it, I also tried a nice dark scheme, to make the sound covers pop ;)
Anyway, it's just a quick concept. Let me know your thoughts. And go try SoundCloud if you are not using it.
