I wasn't expecting a punk song, to be honest. A pleasant surprise. The lighter vocals could be a bit louder so as to be better understood. They're not exactly great singing, but that's the point and they certainly are funny. I definitely prefer the heavier parts, though, especially the part where it suddenly turns almost to metal. I think there could be more variety to them and the lyrics throughout to better illustrate the escalation of toasterfucking. As it is, it starts out pretty hardcore, with the charred dick in the second verse already, so by the end it gets repetitive. Basically, you could have done more of the really heavy grunts and stuff to spice things up because the sung lines are played more for comedy and, while they do sound funny cause of the intonation, it gets a bit grating. So I'd say do that kind of stuff more in the first half and then have the hard lyrics we get at basically the start going in the second half along with the heavier instrumental and trail off less towards the end of the lines to make it a bit more serious so that it's still a funny song, but it doesn't get annoying. Either that or find a way to escalate the humor with the lyrics (probably in a similar way, make them darker), perhaps leading to more of a collapse in the second half.
Keep it up, though, I'd really like to see more from you!
