When you sign up with this link Mog will give you a 14-day trial for their unlimited streaming music service. They normally only give a 7-day trial for new users. I've tested Spotify, Rdio and Mog thoroughly. I prefer Mog's high quality 320kbs streaming and their great iPad app over the others. I also find Mog is better for new music discovery. Mog is available for iPhone/iPod, Andorid and desktop computers.
