Like the rest of the media, I got an email invite from Spotify this morning to a "Big announcement" at 12pm EST / 9am PST on November 30th. (click on the image at left to enlarge) Aside from the fact that CEO Daniel Ek will host the streaming event from New York City along with some special guests, no other details are being provided, to the so far leak-free announcement. What could Spotify have up its sleeve that is that "big"?

I'm betting its some combo of:

• Big partner announcements of mobile or ISP providers offering Spotify as a bundled service.
• Spotify's own US download store. No more sending customers off to iTunes, etc.
• Ticketing and or other "buy" options powered by new partners

What do you think Spotify's big announcement is?
