You're answered your own point there. It's all being done as cheaply as possible. There isn't something that they are going to throw any time or money at to put out great quality material. They are doing it a cheaply as possible in order to make the most money. This is not fan service, it's purely a money making excercise. Surely that's clear by now?

My main gripe is that they clearly have the whole shows recorded, why just give people 3 songs? Just do the whole damn show. They already have the footage it would probably take less time to just put the whole thing out there, than it would to edit it down to 3 tracks. My guess would be is that more songs means more royalties/publishing to pay - so again, a way to do it as cheaply as possible...
