Discover is absolutely useful, but I think Pandora is light years ahead. Is there no way to play the suggestions as a playlist? * iPhone app gives way too little feedback when it becomes unresponsive. I'm never sure if I should click again, wait, try another song etc. Why not add some "gathering data, please wait..", "Low bandwidth/reception.." or similar * iPhone audio cues are hard to differentiate between. Why not make them less similar? When I click the headphone button I'm not sure if that sound meant that I paused, or skipped to the next song. It's like trying to learn morse code * iPad interface. I don't have anything constructive to say about this, but it's just confusing and hard to use for me, and inconsistent with the iPhone.
