I'm not so sure that it's a lack of memorability, but rather oversaturation... I remember back in the days when I started listening to metal, everything was new, fresh and exciting
I feel the same way. The last album I had that with was Schammasch's Hearts of no Light. Ever since there's a lot of stuff coming out that I really like. But nothing I get addicted to.
Usually 10-12 listens is about the max before I’m bored but there’s plenty of older albums with 100+ listens I wanna listen over and over. I don’t know what’s changed.
