Out of curiosity, how did you handle the mobile web with this project? With my pet project, Streeme, I had non-stop issues with the music streaming stopping on lock screens. The root cause was javascript not triggering the next track unless you unlock the device. I also found that formats/codecs could be problematic between mobile devices and different software stacks (mobile firefox, chrome, safari). Is there some alternative interface for this nowadays that doesn't need javascript? Have they settled on a common codec yet? I got pretty fed up with iOS fundamentally changing Safari's HTML5 Audio behaviors with every OS overhaul as it was my main listening device on the bus and at work. Even though it still works on the desktop, mobile clients really killed my passion for trying to make a web based media player.
