Imagine you're a big fan of a certain singer or group. And I mean big fan. Now imagine receiving a phone call that went something like this:

"Hi, is that David? It is? Good. This is so-and-so from such-and-such record company. We know from your blog that you're a big fan of A Certain Singer Or Group. We'd like your opinion: do you think such-and-such a track would make a good single? Do you think it would remix well? You probably know the album better than anyone; which track do you think would make a good single? Really? Good idea. Well, you've been very helpful. Thanks for your input. Oh, and please keep this confidential."

I may have received a phone call just like that yesterday, but if I did, I wouldn't be allowed to tell you about it
