The only really good band on that list is Pink Floyd. Late Beatles is also quite good in its own way, and exceptionally influential, but certainly the early Beatles was very mediocre. Much like Oasis.
The fact that The La's even make Noel Gallagher's top 1000 - let alone number 6 - is testament to the fact that the prick (who also cites Jonny Marr as his biggest influence (lol) and is a very unremarkable guitarist himself) knows nothing about music. Same goes for The Sex Pistols - a bunch of exceptionally untalented knobheads whose only purpose was to take the piss out of establishment (and progressive rock) instead of actually making good, talented, insightful music.
Most of the other bands on that list are also famous, yet generic and not particularly influential in comparison to The Beatles and Pink Floyd. Hell, most of them are nowhere near as influential for all music as the 'founding fathers' of metal and, in turn, most of its hugely diverse subgenres. But of course, Noel Gallagher is an unedcuated, untalented nasty piece of work who would not for one second see the talent and sheer musical diversity involved in playing metal. Millions of unheard of metal guitarists (including several of my personal friends) are so much more accomplished at playing their instruments than Noel Gallagher, and would have more insight and a balanced mind into what constitutes great music than to make an awful, one-sided list such as this.
If the list was actually decent and unbiased; and if Noel Gallagher knew a thing about influential bands; then the likes of Metallica and Led Zep, etc. would have made it into the top 10 without a doubt.
In short: don't pay any attention to anything Noel Gallagher ever says, or anything he ever does. He's an extremely thick person whose intelligence is reflected in both his guitar playing and knowledge of music.
