Despite appearing on the X Factor final, Sir Paul revealed he was impressed by the internet campaign which has made Rage Against The Machine an unlikely Christmas hit.
Sir Paul McCartney has also told how he beat chart contenders Rage Against The Machine in getting the first f-word to number one - by "mistake".
The music legend said he "loves" the fact The Beatles inadvertently achieved the dubious honour without most people even noticing.
The expletive features around three minutes into the 1968 hit Hey Jude.
Talking about the inclusion of the swear word, in his own chart-topper, Sir Paul admitted: "That is true. That was a mistake, man.
"We were doing a backing vocal and it went horribly wrong, and someone said an expletive, and suddenly we did the mix, it was all finished and it was out, and it was only afterwards we noticed, you know?"
Asked by Absolute presenter Geoff Lloyd whether he got a kick out of his first, Sir Paul said: "Well I do love it actually, but the thing is you mustn't put them in on purpose."
Rage Against The Machine are in a tight battle to top the singles chart for Christmas, although X Factor winner Joe McElderry is closing the gap.
McElderry said: "It is just a chart battle at the end of the day. It's just a more documented one than other years.
"Because there's always two songs that go head to head each year and it's close. It's out of my hands and I've got my hands tied."
"It's normally not that kind of record that makes it, it's only every so often that something comes out of left field. I haven't heard the track but I'm into the idea," he said.
