What's the Most Useless Genre Term There Is?

[40FootWolf]

Pretty straightforward. What term is the most useless, i.e does the least to describe the music it labels or is simply downright unnecessary?

[Lameboy19]

99% of them are pretty useful

except slowcore

the -core seems a bit out of place

[ROCKBANDFANATIC7526]

Alt metal

[Rocket2Russia]

indie does nothing to describe the sound of the music

[afterstasis]

improv.

[darkwinterbeast8]

Classic Rock, because it's a station format and not an actual genre.

[voodoo618]

crabcore

[Rocket2Russia]

crabcore

that's actually the absolute best, as it narrows it down to one band every time

[HeyRiles]

Classic rock. It will inevitably change more than any other genre

[voodoo618]

that's actually the absolute best, as it narrows it down to one band every time

Which makes it the most useless.
