Most music produced was always trash, going back as far as records were made. Once, it was the Top 40 and payola, but at least the music producers had a system, more or less, for sorting things out, and bringing you something new on a regular basis, the better to sell more records. Today, I don't think that system works anymore, and you have to do the sorting yourself. What I like to do is go on Amazon and start exploring their MP3 music. Just follow one thread after another, listening to the 15 second samples, and you will survey a remarkable variety of different styles and find quite a bit of new music that is very good.
Many radio stations today are not even interested in playing new songs at all. Even from new releases from artists they aleady play. Or even adding in other “deeper” cuts from albums they play or even adding in other “hits” from the eras they play.
500 songs. Nothing ever changes. EVER.
Houston just lost one of those stations for a rap station.
