X1: Runs 4 apps simultaneously

I've been using spotify since it was available and subscribed as long as I've had a smart phone. So pretty much that. I'm a bit attached to it and even use it over free services.

I have tried Xbox Music, and it's not like I didn't think it was worth the money. It's just that I'm not going to pay for both.

I have to echo this, I used Xbox Music for a while but I just find Spotify much better. Xbox Music isn't bad, it's just Spotify is better for my needs.
 
Spotify has a radio feature. It's not exactly like Smart DJ that creates a playlist queue (iirc), but radio can be used on anything from a single song, to an album or a playlist with random artists, it basically does what XBM does but without the actual playlist (think Pandora). Basically it plays similar artists music. Same difference really.
Cool, it's a good feature for finding new music.

I wonder if XBM will roll together with Nokia Music from Nokia WP's
