Justin Bieber and R Kelly - 'PYD': The song starts off with Bieber repeating the refrain 'PYD, PYD, PYD', which stands for "put you down", but just sounds exactly like he's saying, "puberty, puberty, puberty." Something he was yet to go through when he released this song. R. Kelly's contribution is terrible, but it comes so late in the insufferably boring song that most people have already, surely, switched off.
![Jessie J, Robin Thicke and DJ Cassidy - 'Calling All Hearts': The acting in the video is so excruciatingly awful that we assume, of the 5.5 million people who've watched it, only about 14 made it to the equally excruciating song. Like an even more cheesy version of Sister Sledge's 'We Are Family', the song kicks off with a vaguely bearable verse from Jessie J, whose biggest crime in this song is associating with Robin Thicke. Thicke's verse, when it eventually comes in, is every bit as horrible as you'd expect. By the end, they're just sort of singing over each other like they're given up trying to work together.]()

![David Bowie and Mick Jagger - 'Dancing In The Street': Two of the most talented musicians of their - nay any - generation, and somehow they came together to create this abomination. It's not just the hideous faces Jagger pulls in the video (though they really don't help) it's the lazy, cheesy melody that we can never get out of our head, like musical head lice.]()

Brad Paisley and LL Cool J - 'Accidental Racist': Who'd have thought that an attempt to bury the hatchet of America's legacy of slavery and racism with a five-minute duet could go wrong? Everyone? Well, yes. "If you don't judge my gold chains, I'll forget the iron chains," was described by Billboard as "the most downright offensive line," and the song was parodied on SNL and The Colbert Report, with the song 'Oopsie Daisy Homophobe'.
![Brian May and Dappy - 'Rockstar': This one's a bit sad, because it's all about Dappy's struggle with his overwhelming fame... which, if he ever had, he has now most definitely lost. There's nothing wrong with musicians crossing genres and generations, but this just felt cheap and naff on Queen guitarist Brian May's part, and his mild embarrassment is written on his face throughout the video.]()

Ozzy Osbourne and Kelly Osbourne - 'Changes': We'd like to think their heart is in the right place with this one (though it may very well have been a cold, cynical career move) but there's something a little nauseating about a father / daughter duet with the word "daddy" in it. Plus, one of them needs to turn their bloody chair around, this is no way to have constructive communication.
![John Mayer and Katy Perry 'Who Do You Love': Sometimes the very best musical collaborations spawn from romantic relationships. Gerry Goffin and Carole King, who were married for ten years, wrote some of the best songs of all time. But listening to, and watching the video for, 'Who You Love' feels like being forced to spend an evening with a couple you barely know, while they showcase increasingly inappropriate levels of PDA, while a vacuous ballad plays in the background that they profess to be]()

But listening to, and watching the video for, 'Who You Love' feels like being forced to spend an evening with a couple you barely know, while they showcase increasingly inappropriate levels of PDA, while a vacuous ballad plays in the background that they profess to be "our song!" The pair have since split.

Lil Wayne and Paris Hilton - 'Good Time': You've got to hand it to Paris Hilton, she's not attempting to do anything beyond her repertoire. Normally, we'd be supportive of some harmlessly inane pop, but somewhere among the asonine lyrics, offensive EDM beat, Lil Wayne's hideously lazy rap and the blatant plagiarism of "It's Paris Hilton, bitch" it lost us.

Paul McCartney and Stevie Wonder - 'Ebony & Ivory': You've got to admire the absolute earnestness of this song's intentions. It's just, its melody is atrocious, and lyrics like "People are the same wherever we go" suggest a non-existent homogeneity. Plus you really want it to go somewhere and fulfil the promise of its message and the true greatness of both artists.
