(There was a cover version by a musician called "Adele" here, previously.)
Lost the Adele version already, on account of copyright violation. Yet you can go to YouTube and watch it. Isn't streaming something to people you have an influence on just free publicity for an artist, so that those people may buy the album? I don't understand the strongarm tactics of the music industry a-holes. I just love music and want to share it with people; I'm not filling my site with ads and trying to make a nickel off anything. If the people I know like something enough that I put up, they are likely to buy it legally. Everyone I know well will, if they have money. If they don't, they wouldn't buy it anyway! Duh...
Well, so much for the comparison. By the way, about the Mu reference...
More accurate version
Basically saying "mu!" to a question is to "unask" the question. Useful for paradoxes and being questioned by the FBI.
