OK, I need to clarify about U2: I liked “One” and “With our without you” very much, the first several hundred times I heared it. But after I heared it several thousand times, I got a little fed up with it.
Great songs, but it made me not listen to radio anymore. Overexposure destroys passion!
So, these are some lesser known tracks that are also quite repetitive and use not so many notes too…
