I want to like it, but it's not doing what I want. I have a ton of music on my Android phone, but app won't sync from a phone, only from a desktop computer. The corroloary to this is that music I get from outside the Android market (e.g. friends, random downloads, Amazon MP3) is invisible to the cloud unless I copy it manually.

And the Linux app sucks rocks. My memory is that it's an enormous pain to get installed on F16/x86-64. It doesn't understand the standard proxy environment variables or gconf settings, and in fact when used behind a proxy, THE UI LOCKS UP SOLID a few seconds after starting. So I can't use it at work. (Because who wants to listen to music at work?)

I wouldn't even care, except that I have to use the desktop app. Even things that I'd think would work as web apps aren't there. You can't upload from a web app. You can't manage play lists from a web app.

That said, the Android player app is actually not bad at all, and I do use it. But the cloud side of the equation is a total fail from my perspective.
