According to the thread linked here, there has been some communication with them. I thought I'd open this enhancement request so it doesn't get lost in the forum. 

This is a great service. I use it a lot to sample music before buying. They also sell music, usually a bit cheaper than Amazon.com. You can match your music library with what is on their servers or upload your music for unlimited streaming.

I'd probably explore and buy more music from them, if I could use the service from the comfort of my recliner instead of at the computer when I should be working.
