The Deal (via Ad-Supported Music Central) has an article with some stats on SpiralFrog. In the last week of June, founder and chairman Joe Mohen predicted six million unique visitors for the month. The problem with its catalog is evident in the fact that only 50% of searches were fulfilled.

SpiralFrog is available only in the U.S. and Canada, which have a combined population of 333 million. With six million uniques, that's 1.8% of all citizens. In both countries, there are about a combined 88 million people between the ages of 15 and 34. Again assuming six million uniques, the service is hitting about 7.4% of all people from ages 15 to 34 -- almost one in 14. We don't know anything about length of visit or total tracks downloaded, but that is a very large ratio for such a young and incomplete music destination. (My rough math assumes one user per household for the sake of simplicity.)
