It was good when it was ad-funded and free to users. They obviously weren't making enough money from it that way. Shame because I didn't mind the ads and saw the format as a natural successor to radio. Great way to discover music (new and old) too.
Don't see the point in subscribing for a fixed price, and more to the point, can't justify paying for a service like that when I'm spending £££ each month on Sky (TV, Broadband and landline) and LoveFilm. You just can't do it all, eh?
