Foo Fighters are not my cup of tea however I saw them live and it was an okay show. Also they make no attempt to disguise themselves. I have seen any number of interviews with Grohl where he stated that the Foo is a pop rock band and nothing more.
As for Disturbed. I saw them live like 5 years ago in a small club. It was possibly the saddest thing I've ever seen. The music was *****, they walked around like big men but when they got off the stage the lead singer is like 5'2. I chatted with him for a bit and it was like speaking to a munchkin.
the Tragically Hip are greater than all.
As for the Beatles they blessed us with a number of a catchy tunes and the gem that is the "I am Sam" soundtrack full of their covers. However that still doesnt excuse the monstrosity of a song that is "Taxman" off the Revolver album. That song is pure *** in song form.
