I swear buy it and for the price of 1 album a month you get access to 'almost' anything you can imagine. Yes there are still a few annoying holes in artists back catalog but hey.
I twin my with my HTC Desire, listen offline feature is really handy..no need for a 3g of Wi-fi connection while out driving or walking. Obviously you'll need a Android or Apple product in order to take advantage. I also have it running on my laptop and my Partners Galaxy S2 is synced as well. As long as one of us is in 'Offline Mode' while listening (she users her in a her Car) it didoes seem to get upset at basically 4 separate devices using the same account.
There's some annoyances but there we are its less than an Albums Price away
and something they didn't talk about much in the UK
You can drag and drop any supported audio file into Spotify and you can sync it and take it with you...Protected files or indeed un-protected files ..
