Personally, I think they are getting MUCH better with a little age and maturity. "Heathen Chemistry" is quite a good album, and a good step even further away from the crap that was "Be Here Now." The lyrics are getting better, the overblown "we are rockstars" crap is going away, and, oddest of all, people other than Noel are getting to write songs now. And some of them ("Songbird" in particular) are pretty good.
Also, since they closed the covers thread: Oasis' cover of I am the Walrus rocks.
"I'm bi a lot of things, but lingual's not one of them."
Heathen Chemistry is a really strong album in my opinion. Has some real nice rockers like the hindu times and hung in a bad place. Stop crying you your heart and Little by Little are two really good ballads. Even Liam's songs are decent. I don't like better man but Songbird and Born on a different cloud are actually quite good. If you are a fan of Oasis that has put off by their past two albums, you should pick up HC. I think you will be pleasantly surprised.
