Sell. CDs. From. Indie. And. Commercial. Artists.
Sell. DVDs. Next to. Movie Trailers.
Take a small percentage of the sales revenue. There's got to be a huge population of people who watch movie trailers, music videos, covers of popular songs, and original work by indie artists trying to get exposure. Relatively, the sample players on Amazon and Barnes and Noble suck so bad. This is the perfect way to test drive media before buying - if Google just brought it all onto one platform and standardized the checkout/distribution process.... just think. Omg. They'd be even richer than they already are.
I guess they already sell mp3s, but I think it's about getting all these people who make new music and don't have a good way to distribute it, make it buyable.
Just random brainstorming on a Wednesday evening.
