Okay, some that I like that others do not:
Flaming Lips: Check out Transmissions from the Satillite Heart, it is amazing. Check out the layering of instruments, and all the fun things going on. Fav song, Pilot can from the queer of god. Check out the dense guitars and all the fun stuff they are doing, it is amazing.
Bloc Party. I hate this cd. It is poorly mixed in my opinion. The material it has underneigth is amazing. They are a great band, but they were wimps and got someone to mix their album to where it sounds so annoyingly compressed that I despise the record. If you are willing to listen to the songs and not the stupid overcompressed mix it is a great album. It took me several listens to figure this out.
There are others that I can also talk about but these two came to the top of the list.
ps. I have seen over 1000 bands live (IIRC).
