Every day, Rocks Off is reminded that we should have taken rapping a bit more seriously in our younger days. Today's friendly reminder comes in the way of a report saying that Eminem cashed a $3 million check for two nights of work at the UK's V Fest.

Em's scenario isn't typical, though. Concert fees run the gamut from $50 (for amateur wedding singers) to $150,000 (for Drake or Weezer). Most artists get a base pay during the booking; the sum rises if you sell a pissload of tickets and merchandise. Say what you want about the music business, the live arena remains a lucrative area for most musicians. Not to mention the multi-billion dollar performance-rights industry.

We'll leave you with this list of eye-popping performance tags, while we go dig in the basement for that dusty ol' rhyme book.

Justin Bieber: He may look and sound like a girl, but Justin Bieber is caking. Last year, the Biebz topped Smoking Gun's list of highest-grossing performers. His asking price of $300,000 could buy you some Egyptian charm.

KISS: The Bieber Machine is dirt-cheap compared to these freaky clowns. Their concert tag is a hefty $500,000 per night.

Ivete Sangalo: Sangalo is Brazil's answer to Shakira, if you will. The Latin Grammy-winning singer is not cheap, though. Expert Tip: Don't book her on New Year's eve. Sangalo demands $275,000 for regular shows, but special occasions will run you $1 million.

Rascal Flatts: Country-rock gurglers Rascal Flatts will grace your party for a mere $702,000. Well, that was their asking price before they had a song with Justin Bieber. Now they probably charge $2 million, plus Converse shoes in every color.

Mariah Carey: Chicken-faced Libyan nutcase Gaddafi/Gadhaffi/Quadaffy/Kadafy once paid Mariah Carey $1 million to sing four songs on the Caribbean island of St. Bart's on New Year's Eve 2008. Carey said she didn't realize she was performing for the Libyan neanderthal at the time. "I was naive and unaware of who I was booked to perform for," read her statement. El Oh El. For $1 million we'd do the show blindfolded, too.

Michael Jackson You can't discuss eye-popping performance fees without mention the king of eye-popping everything. In 1996, the Sultan of Brunei hired MJ to entertain guests at his birthday bash at the Jerudong Amusement. Jackson reportedly took home a $20 million check for the gig.
