I like WTF. It's heavy. It's fast and it was fresh after R2R. And, it was the first time that Slipknot plagiarized IF.
The fact that they did and nobody batted an eyelid says it all tbh, it was a very nu-metal sounding track. Not really my kind of music, but I did like some of the harmonised melodies in the middle of WTF. Chorus is awful, imo. Not too dissimilar to the State of Slow Decay chorus actually, when you put them side by side. Anders/IF Producer just uses ProTools better now.
I do like the "I lost my visual, 'cause all you fucks are in my way" line Anders trying to be edgy and cool with his aggression and swearing... like an angsty American teenager, one might say. Very amusing. Totally natural though, nothing to do with directing the music to a different audience. Not sure any other IF songs drop the f bomb? Can't think of any others off the top of my head.
