Not really sure where this lives but seeing as there is an Android app for it then it can live here.

I have two invites available after being invited myself this morning. First in first served.

So far it's quite smooth, faster than grooveshark however I needed to use my VPN to set it up. Thankfully it's not required to use it after setup.

When you select what types of music you like to listen to it automatically adds a number of songs under those genres to your account for you to listen to.

There is a nice iTunes type 'genius' mix option available as well. I haven't uploaded a large amount of music to the 'cloud' but what I have added doesn't seem to work with this feature. Given that the band is New Zealand based i'm not surprised that it might not be in any system. The 'free' songs do work. 

I notice that the service will likely incur a 'fee' at some point which makes it less awesome for me thanks to our data rates being obscene.

The Android app can be set to use wifi only for cloud based songs which is handy but it is otherwise an unremarkable player compared with UberMusic or PowerAMP.
