Eternally cool bands?

[ShangriLaTroubl]

I thought I would ask you guys' opinions on this..there are many excellent bands/artists that have been around forever, some I love some I don't. The question is which artists/bands do you think have remained eternally "cool" ?

Now when I say "cool" I mean to most people...there are plenty of bands I love and think are cool but not to most...and they probably have just as many fans...but for some reason there are some bands that it's ALWAYS cool to like...who do you think?

My list is here :

Aerosmith
U2
Beetles
Rolling Stones
Metallica
