Music blog Musically has jumped on the new accounts of Spotify’s UK Limited company to reveal some interesting figures, to say the least. The accounts also reveal that at the end of 2009, Spotify’s parent company Spotify Technology SA was negotiating further funding.

The most interesting stat, to me at least is that Spotify started 2009 with around one million users and ended with seven million users across Europe, of whom over 250,000 were paid-up subscribers. That is a sevenfold increase.

The latest official Spotify numbers, says the company, are that they had over 10 million registered users (in October this year) and over 500,000 subscribers across Europe (a figure revealed in June).

But assuming the growth rate in the second year was slower, let’s call it a two to threefold increase, then Spotify could well be heading toward 15 million users by the end of the year, and 750,000 to 1 million paying subscribers. Let’s hope for their sake they are.
