2 months ago, April 22nd to be precise, Last.FM switched over to a payment model. This, I would imagine would have had a significant effect on their traffic, but lets have a look at what Nielsen have to say.

According to Nielsen NetView Last.FM actually saw their most significant monthly increase since September of 08. I am unsure of whether this is a result of increased interest due to news of the payment model being introduced or whether they have invested in some paid media to drive traffic. Either way I would be very interested to know how the uptake in membership has been given the vast array of competing services that still offer free access (not to mention the vast amount of online users who simply pirate their music).
Does anyone have any figures around Last.FM’s paid vs free membership levels in Australia?
