I think you answered your own question when you wrote "occasional commercials."Pandora is trying a different approach than terrestrial radio: rather than ten minutes of commercials an hour, they're keeping them really sparse. This allows them to keep the site for free for most people, and ask the people like you who really enjoy them (since you listen to more than 30 hours a month) to help financially.I disagree with you that this is wanting to have it both ways. It might be you who want it both ways... you want it to be free, like commercial radio, but you also like the fact that commercials are rare.As for your "why so greedy?" question -- you should keep in mind that nobody at Pandora is making lots of money. They've had to lay off some staffers and it's been a struggle for them -- as it has been for all network radio stations -- to deal with the whole royalty issue. It's less greed, and more like a struggle for survival. I disagree with you that it's a "retarded notion" and I believe that your "WTF?" is a little harsh.
