The former Oasis star claimed that today's acts pale in comparison to those from the Britpop era
"The days of Oasis and Blur were the last great assault on the charts by alternative music. Christmas Top of the Pops was dreadful," he said, according to the Sunday Mirror.
"Every song sounded like it came from the same field of music. There was a rap in there somewhere, everyone sang in a transatlantic soul voice and it was rubbish.
"The Britpop thing was vastly different. We were all great live bands, and that's gone now."
Gallagher added that Oasis are among the greatest bands of all time alongside The Beatles and the Sex Pistols.
He recently admitted that his solo album getting to number one was the best day of his life.
