Slipknot vocalist and frontman Corey Taylor has laid the blame for the explosion of file sharing on record labels rather than the file sharers themselves according to this Kerrang article.
Why would you blame (people who download music)? Half the fucking albums that are out there are shit. I don't download, but at the same time, I don't buy new music 'cause it all sucks. Okay, there's a handful of bands that I buy, but other than that, I just buy old shitt because old shit is good.
I think it's the quality of the product. If record companies would stop giving any fucking mook (idiot) on the street with a fringe a record deal or their own record label, maybe you would sell more fucking albums, dipshits.
