What media file type does Rhapsody use?

I had been using Download Helper to download my music from Rhapsody, but that no longer works. I have deduced the problem as being that Rhapsody changed their music type to something that is unrecognizable by Download Helper. I need to know the media file type to download music again. I have read that it is AAC and RAX, but I believe that Rhapsody just recently changed last month and I can find no mention of the new file type. Please help!
