Thing is all bands nomatter what their style, suffer the same fate and its easy to forget they are in the entertainment business not in the 'we're here to change the world business'
They all had a shed load of good songs as they grew up and poured them into their first two albums and then had to write to order which means they'll then struggle to - either write as good as or try to change direction to resell themselves, which is very difficult to do and the fans will feel they've been 'let down'
All bands will have some great tunes and then tail off.
We get so precious about it but if you respect that every musician has a chance and shines for a while then it at least creates a huge variety for us listeners / consumers to pick and choose
None of these bands are shit and some have given us great moments and even after 6/7 albums still surprise us with another great tune
I'm still shocked at the vehemence / hatred some of them get
No band can setup write fantastically and then continue with it for 20 years. You have to go through lesser creative periods
For me Coldplay Oasis U2 especially early on have, even amongst just those three bands given us a huge collection of great stuff
On a quality control basis I find it difficult to understand that Queen are anything less than heavyweights in the rock music world
(the only other point I'd make is please for fk sakes don't get JCurr joggin on about Radiohead or this thread will end up nailed to the dark room floor
