Very nice! I paid for the desktop app once but I don't feel like it adds anything to the experience other than support for media keys, so it's kind of just a waste of money. If they were to add some exclusive features to the app I might pay for it again.
Until then, your app is an awesome solution. So far it's working great, just one minor annoyance; the pause media key works as expected but when I press it again to resume play it starts from the beginning of the song again.
