On air compression
It's not necessarily all the fault of the production on the song, it could be the radio station you're listening to.
If you listen to most radio stations playing modern pop it's quite obvious that they are compressing (dynamic range compression, rather than digital) the hell out of everything. This means everything retains a CONSTANT PEAK LEVEL OF VOLUME WITH ZERO DYNAMICS THAT NEVER CEASES STRAIGHT THROUGH EVERY SONG, INTO THE NEWS AND OUT THE OTHER END INTO THE ADVERTS AND HERE'S THE NEW ONE BY THE CHAINSMOKERS AND NOW SOME DJ BANTER LAYERED OVER THE TOP WHILE ALL THE TIME MAINTAINING THE SAME LEVELS THROUGHOUT BECAUSE WE ARE SCARED YOUR FICKLE ATTENTION SPAN MAY SWITCH OFF.
It's truly dreadful, and once you notice it it can't be ignored. And yes I do realise I'm sounding like an old fart, but that doesn't make it any less true.
