I signed up based on offered content. No more than a week to my subscription and without any notice, about 90% of their offered content was taken down and made unavailable. I contacted them to cancel my subscription, but they wouldn't do it.
So they lure me in with promises, but once the payment goes through they don't deliver and keep your money.
After Googling, I also saw that labels complained that Emusic hasn't paid them.
Beware!
