For the record this app works great with current release of Crossover. I've actually used it since Crossover 6.x but it used to have problems where you couldn't minimize it. With 8.x you can now minimize and restore the app even under things like compiz/kde4 desktop effects. The advantage of this app over live365's web page player is that you get MP3Pro stream capability instead of just mp3 - this matters to paid subscribers.
