Still, I think the point to realise is that Oasis make one kind of song, and that's it, which is what people are getting at. Good artists have the skill to produce a variety of different songs, and not just rehash the same old rubbish. Nothing wrong with having a few songs that have a similar style, but when the entirety of your career is made up of one idea looped over and over, that's when you have no merit.
Then you haven't listened to enough Oasis. But of course why would you want to waste your time doing something silly like that
