Thank you for making this! The existing dropbox music apps are terrible, you have to select songs one by one instead of streaming entire directories. Thank you. Going to download when I get home.
I don't mean to steal Tunebox's thunder, but Audiogalaxy (http://www.audiogalaxy.com) might be another solution to your problems. It's completely free, supports almost all audio formats and has a ridiculously high max-song limit (200K+). Works on Android and browsers, too.
Thanks for mentioning. I have heard of the site, but never checked out what it was for. Looks nice, I'm going to try it out.
Does anyone know how they handle lossless? It says in the FAQ they support FLAC, which all my music is encoded in. Google Music transcodes it. I can't seem to find what Audio Galaxy does. I'm assuming they do something similar, but they don't say to what or what bitrate.
