Ah, so it's a Gator[1] clone. Great, something else to warn people about. Gator was allegedly installed "voluntarily", but it turned out that wasn't how it usually happened...

The legal snafu with MegaKey is that it REPLACES ads, which, depending on situation, could easily be illegal contract interference. If it steps on banner ads and contracted ad real-estate on websites (Facebook, for example) he's stealing revenue. I'd assume if he were confronted with this, he'd play the "champion of the people" card, stating the original ads were placed there by greedy, unethical corporations and thus he's a hero. (Last part is my opinion, first part is an actual legal problem ;)

Thanks this if the first I've heard of it. I could see that being an interesting proposition for many people (the ones who refuse to pay for any music). As someone who still buys music and subscribes to Spotify Premium there's no way I would use it.

Spotify is great, unless you happen to be part of the 90% of the world population that they don't support.

It will get their eventually. It took iTunes a long time too but they are, I think, now the biggest music retailer.

I hope it's easy to find a list of MegaKey advertisers, so I know not to buy anything from any of them.
