yup supergrass and oasis have had some pretty cool tunes. you can guarantee that an oasis tune will be being sung at numerous drunken sing-alongs, although i don't hold either in the same regard as people like floyd, led zep, the beatles, CSN&Y (and all of their other conquests), hendrix, clapton, grateful dead etc.
i don't think music will ever be as good as it was in the 60s and early 70s
