Two interesting quotes from the post:
But the reason imeem is in such dire financial straits is because of the crushing payments to music labels it has to dole out for every song streamed from its site.
According to comScore, imeem’s U.S. traffic has come down about 25 percent off its peak last July. As of March, 2009 it was at 5.3 million unique visitors in the U.S. and 24 million worldwide. In the perverse world of music streaming licensing, the bigger your audience, the more money you lose.
