R & B is ALL ABOUT catchy hooks now rather than lyrics of substance.
Those people get a LOT less airplay than "I Bet The Neighbors Know My Name".
Is popular music today better than it was 10 years ago?
Heck no. Autotuning, cursing every other word, and mumbling generic lyrics is no way near good as classics of early 2000s (and even better yet the 90s).
Regarding the original post...I absolutely hate that when we were dealing with record labels, trying to get a deal...we wrote some INCREDIBLY radio friendly songs, but included guitar solos. The labels all told us that guitar solos would never come back in style...so we went our own way, put all of those mainstream songs in a file for later use...and released an album thats not as mainstream...and next thing you know guitar solos are back again...
The music when your young is generally the music you "connect" to.
