Everyone will have their own hates... here is a selection of mine.
The Smiths - I just don't get it. Never have done, never will. Legions disagree.

Genesis / Phil Collins - Makes me feel physically sick within seconds.

Jamie Cullum - Same as Phil...

Vanilla - No Way No Way indeed. Thankfully a one 'hit' abomination that has rarely troubled me since, however it is surely the nadir of recorded music alongside...

All novelty Euro Dance - Crazy Frog, that song from LeekSpin, Basshunter (who is begging for a strikethrough gag). There is no greater musical evil that I have encountered. None. Nothing makes me retch and convulse with incomprehensible rage in quite the same way.

Does It Offend You, Yeah? - I have never heard their music. They are included for the name alone. It screams art school pricks with stupid hair and tight trousers that think they are really cool and ironic and finish all sentences with a question, yeah? I may be wrong. I suspect I am not.

So, so much more I could mention but I've made myself sick now so I'll stop for a quick dry heave.

You read my mind.
I was just about to nominate Does It Offend You, Yeah? for the same reason.

"Does it offend you, yeah?"...
... is a quote from The Office. Their music is actually pretty good.

that song from leekspin
Is a modern take on an old Finnish song! Basshunter can get fucked though

Basshunter
Apparently Basshunter DID go get fucked. Quite recently.

He just didn't bother asking for consent first (allegedly).

I could totally belive that
had to watch celeb big brother with the missus and he came across as a bit rapey, not to mention weird.
