I'll add the note about using fastern9 and problem with sounds, thedead1440 mentioned it to me before.

I want to know if anyone is able to use it successfully on the N900?

The issues I have no idea how to fix (and probably can't be fixed) pause while rotating, pause while pressing the power button.

I will try to implement this for the next release:
* Command line parsing to start playing on launch
* Play controls with headset (can't test as I don't have one)
* Initial login and profile support.
* Share current mix url (n9 only)
