Metal fans are the most loyal fans in music. Exhibit A: Last week had major album releases from a variety of successful acts across the musical spectrum like the much discussed and promoted  Pearl Jam album, gangster rappers  Mobb Deep (now signed to G-Unit), and large chested folk-pop singer songwriter Jewel. Which one of those acts had the number one album? None of them. Number one went to Tool who sold 564,000 thousand albums or more then the above mentioned 3 acts combined.
