While that is certainly true, it just seems to me that the amount of variety in music has dropped in recent years. You can find this music if you look for it (the great part of modern music), but I almost never hear people to listen to stuff like Herb Alpert, Booker T and the M.G.'s, or their modern equivalents, just for an example. While instrumental music is not everyone's thing, it was just as popular as the best pop music in it's day. There was a lot more variety.
These days, almost every song that gets airplay has the same common elements and I get bored with it. We already people casting aside music from the 2000's in favour of music from previous decades.
