I meant S-tier as in ranking. If you look at tier lists on the internet, they will often rank things using letters. I was basically just saying that I consider them to be bands of the highest tier, I’ve attached a link to show you what I mean.
I just discovered them recently on a spotify suggestion. So glad. Sometimes things just work out. It's a numbers game. I've probably turned away 95% of what spotify recommends. I've had premium for a decade and the discover weekly playlist is still hit or miss. Sometimes I see a pattern, like every other week there may be a good song.
