As of April 23rd, its working great with Spotify

I see several reviews saying that it isnt working with Spotify. Its working fine here, Im using it right now.

Theres a nice, free preference pane that will let you use the Mac’s keyboards media keys with the app.

Ive used this app for a long time and it has continually been developed and improved. Id recommend it for anyone who wants a menu-bar-based controller and display of the current track.

(Reminder: App developers cant respond to reviews, so if you have a problem with an any -- any app -- contact the developers, dont abuse the review system!)
