The marketing depts will ruin music. They’re so focused on market segmentation that they will eventually prevent new genres of music from performing.
See American stations in the 50s. They were so racially segregated that many white people never heard rock and roll. It took the British R&B, blues and early rock bands who were importing and who were influenced by the black music i.e The Beatles, Stones etc to essentially sell the black music back to American white audiences resulting in modern rock and roll.
In addition, black and Latino gay music (early dance) rose from the the embers of disco and pioneers like Pete Tong made it popular here. A whole culture in the UK was born from dance/rave music.
If you segment and niche everything for advertising purposes, you don’t get cross pollination and new types of music. Everyone just stays in their box not being exposed to anything new.
One of the reasons I like 6music is that it does try to play a variety of music. Some you’ll love, some you’ll like, some you’ll dislike and some you’ll hate and that’s a good thing as it shows that you’re being exposed to something you wouldn’t necessarily put on your Spotify playlist. I only recently discovered I actually liked modern Jazz (Kamazi Washington) through them and I hadn’t really given it any time before as a genre.
Unfortunately pretty much every other station seems to start off with a marketing dept working out which demographic they want to target re advertising. If you have a station which pretty much only hires white middle aged men, playing songs by middle aged white men and advertises Gillette razors and Stella Artois every ad break, there will be no surprise when the listeners pick Oasis for 20% of their top 100 songs. They’re not being challenged and they’re not the type that want to be adventurous in any way shape or form.
