Music is completely subjective to the listener's preference. That said, I find: Pink Floyd; U2; Red Hot Chilli Peppers; and The Police the most overrated. One artist that really shaped the world but really didn't do it himself was Elvis (Presley, not Costello) who, like later in the 1980's Stock, Aitken and Waterman era of endless "creation" of people to perform their hits, just performed other people's music. I think Eminem uses a lyric along the lines of "being the first white man since Elvis Presley to use black music to make him wealthy." Current excellent and popular lyricists and songwriters, like the aging Eminem above, include Taylor Swift, Ed Sheeran, Adele, and Lady GaGa - whose music doesn't necessarily appeal to me - but at least they write and perform their own stuff. Albeit for a generation (or more) below me. And it resonates with a wider crowd. The four bands I listed at the head of this diatribe just never did it for me even though their following was huge in comparison to say REM, The Cure, Joy Division, and Crowded House. Which I also don't rate. But, hey! I like 1970s British rock, and the saccharine <deleted> of the fifties and the sixties.
