I agree. I don't think that's a diverse array of music at all.
If you don't want to look at the picture, thats a range of Pink Floyd, Metallica, The Outlaws, Elton John, Derek and the Dominos, Bon Jovi, Elvis, Paul McCartney, Merle Haggard, Rush, Billie Eilish, Joe Satriani, Slaughter, Vivaldi, Ted Nugent, The Eagles, Nat "King" Cole, Vince Guaraldi Trio, Jethro Tull, Tom Petty, and more Vivaldi.
That picture is only what I own on cassette. So no Stevie Wonder or Eminem in that picture. No Zeppelin or Spike Jones. And its missing some others that I enjoy as well but I digress.
So there's a picture of just a handful of random albums that I own and enjoy greatly. Your call TGP, is that a "diverse" musical library at first glance?
