I have been using Spotify for a good few months now as a premium user (£10 per month) and get issued with a small number of invites each month which I can send to anyone interested in trying it out.

 

The invite allows you to download their free version of Spotify which includes a 30 second advert played between every third or so track you listen to.

 

More info here http://www.spotify.com/uk/new-user/ - http://www.spotify.com/uk/new-user/  if you would like an invite just send me an email address and I will do the rest while I still have some to give :)

 

I have found it to be excellent, particularly as I am able to use it on my mobile too, including tracks for listening offline, all for less than the cost of a new CD purchase a month.

 

I have access to Opeth, Isis, Genesis, IQ albums etc., as and when I want them.

 

No Led Zep or Pink Floyd yet however there is a 'Chill out' collection of Pink Floyd tracks which is extremely good.
