Do you support playlists?

Ubuntu One mobile music streaming does not support creating playlists at this time. How do you know about a file’s artist and album information? As soon as MP3 files are added to your personal cloud, our server software scans the files for ID3 tags (artist, album, song title, track #, song duration, etc.). When it completes each one, they'll appear as a streamable file on your mobile phone.
