10 Music Artists Who Absolutely Hate Each Other

10. John Lennon and Paul McCartney

When you're in a band with a bunch of egos, things are already testy before you even play a note of music. Even if you're all on good terms, there's often a fine line between constructive criticism and letting your holier than thou attitude show a little bit too much. So...amplify that times 5 and you get the harshness of what John Lennon and Paul McCartney had towards the end of the '60s.

While still being an admirer of each others' material, the artistic mindsets of both of these men were practically on life support by the time the Beatles called it quits. Since Lennon was gearing towards artful rock with Yoko Ono, McCartney began looking more and more like a dictator in between record sessions, which was detailed a little too much in the Let It Be film. Though Abbey Road was the final note most of us wanted from the Fabs, the next few years would be really shaky for our lads from Liverpool.

Lashing out in song at each other, most of the first offerings from both Lennon and McCartney featured jabs at each other, from McCartney calling out Lennon's advocate stance on Too Many People to Lennon taking him to task for dictating on How Do You Sleep?. Then again, the late '70s did show them at least on better terms before Lennon was killed at the beginning of the '80s. As much as these guys didn't have anything nice to say to each other, it's nice to know that there wasn't any bad blood taken to the grave.
