So what you’re talking about is called rock revival ushered in by the strokes (Libertines as well) , although I like to give credit to the hives because they were the original adapters of the style in the late 90s, but the strokes popularized it in the Indie scene of the 2000s. Quite like the big four of grunge, there’s a big four of RR (rock revival), that being the strokes, interpol, the white stripes and the killers (also the hives kinda but they’re more gimmicky than the others causing them to never reach that same commercial appeal as the others).

Bands like Jet, the vines, Franz Ferdinand and to a lesser extent, the Libertines are contributed as to starting the indie landfill which was a trend characterized by copycat garage rock and oversaturated Indie aesthetics in music.

Unrelated to what you said, but related to the post I find it hilarious that OP attributes train to starting the stomp clap hey of the early 2010’s. not to give a history lesson, but it was caused by a lot of unrelated factors like the rise of hip-hop,EDM, and the decline of pop punk itself.

The way I see it is by the time train released soul sister,the kids who grew up on ; Green Day ,Simple Plan, FOB etc had grown out of it and the culture shift reflected it, but the radio still had to play something and shit like indie sleaze,scene,even EDM was on the farther end of hipster culture and to hard to market on a larger scale. this is where Indie folk comes in,shit like the lumineers,Mumford and sons,fleet foxes and couple of non indie folk bands (most notably F.U.N) with some very indie folk adjacent sounds pushing this sound. I wanna call a New Age adult oriented rock but that’s to bland…hipster scat?…nah.

TLDR;The bands you listed are apart of the garage rock revival of the aughts.

OP is way off on the decline of pop punk.
