I was looking at that and raised it with them. No not possible, said they'd have their developers look at it, can't believe I'm the first to ask though so not expecting anything to happen.
You can do it with Deezer but only having taken a family subscription, was hoping to be able to try it out on the free version first. I've paid 99p for 3 months to check it out, seems pretty similar, actually prefer it for finding original albums that don't have unnecessary bonus tracks fillers tagged on the end.
