George Harrison didn’t enjoy listening to The Beatles‘ music on CD. He preferred to listen to his band’s music some other way.
During a 1987 interview with Charles Bermant (per George Harrison on George Harrison: Interviews and Encounters), George spoke about how he thought The Beatles’ music sounded on CD. He liked the older versions better.
“I did buy a CD player when they issued them, yeah,” George explained. “I listened to some of them. I still prefer the old versions, how I remember them on vinyl. There’s a lot of stuff that you can hear now that’s good.
“In some cases, there’s a lot of stuff that you shouldn’t hear so loudly, that’s somehow come out in the mix. On Sgt. Pepper I keep hearing this horrible-sounding tamborine that leaps out of the right speaker. It was obviously in the original mix, but it was never that loud.”
