iPhone: Dropbox and Google Drive make for great places to store your music so you can access it from anywhere, but you still need something to play the music. Vibe Cloud Music Player does just that.
Vibe Cloud Music Player is pretty simple, but it does the job. Once you point it to your Dropbox, Drive or Mega account, it automatically organises all your MP3s into songs, albums and artists. From there, you can stream those songs or download them for offline play.
You get a few basic music controls, including seek, repeat, shuffle and playlists. If you want to stream more than a few songs, you'll need to pay $4.99 to unlock the full version.
