Worst music I've ever heard is probably anything from Sepultura's Roots.
Imagine this. Some people went to a flea market in the jungle, and got a bunch of **** for 10 dollars. They hire 2 djs, and take them to a secluded recording studio. They take all the **** (And 1, not 2, but one of the djs) and beat them with a sledgehammer (All of this is being recorded, remember?). Afterwards, they tell the other dj to remix the sounds. And bam, you have Sepultura's Roots.
And possibly the worst of the album...
I love Roots, it's a great metal album by a great metal band. Seeing as how you like power metal and all, I wouldn't expect you to like it. Ratamahatta is awesome too, I love blasting it through 5.1 surround sound :D
