Way too little.
It's one thing to have a category killer domain name in an industry that's difficult to profit off of... but it's another thing to have a name for such a well-established category, that prompts the purchase of songs or music videos, which is all profit, given the lack of overhead, very inexpensive to buy, and habitual to purchase by the hordes. The high-capacity iPods are a testament to this.
The music videos act as a catalyst to prompt the song purchase. I think that whoever bought this has themselves a timeless investment and can prepare to profit off of not just song purchases, but advertising revenue as well.
