Me, my brother, and two of my friends use it.
I love it, I used to use Pandora before it became US only.
I hope this stays available in the UK, it's fantastic.
Needs a bigger database but, that'll come in time.
Really don't mind the odd add, and so far they've all been good ones like blood donors etc.
As long as Cillit Bang don't start advertising it, we'll be fine :D
