I've never subscribed to a streaming music service before but I'm pretty pumped to try this out. I already use Google Music as my main player so it's kind of a no brainer for me. 30 day free trial, and early adopter fee of $7.99 a month; goes up to $9.99 after June 30.

Anyone else interested? I assume if you're already using rdio or spotify there wouldn't be much motivation to switch.
