I can now see why Apple approved this app -- it's not that useful actually. The sound quality from a 3G-streamed song is a bit faint. What's worse, I never thought I'd feel so crippled having a music player that can't run as a bg process. I can't use Spotify and at the same time, for instance, read/write email or write this post. I'm sorry to say the Spotify iPhone app is not for me...
