I've been seeing people say that Katy's songs left no impact, but after "Dark Horse" was released there were literally 4 songs from mainstream artists that cloned the trap beat in the years 2014-2015. (Kingdome Come, Black Widow, Get On Your Knees, and Numb(by Nick J)).

EDIT: more songs that were impacted by Dark Horse: http://atrl.net/?p=31364508

So would you say Katy's "Dark Horse" left an impact?

it invented trap

Yes. If Satan exists, it would be his favourite song.

it introduced trap to the mainstream

No. Trap music wasn't even that big of a trend afterward. There were one or two knockoffs of the song but I really don't think inspiring Demi Lovato and Iggy Azalea album tracks = impacting music or starting a trend

Not really. It was just another lil quick single.

It helped in pioneering elements of trap in pop music, as shown by these examples, so of course!

Iggy's clone of the song was a #3 peaking smash on the BBH100

This.

why dont u ask her yourself?

No, and no shade but none of Katy song have impact or longevity. She's the type of artist who makes hits for the now instead of making art she can preform 20 years from now. Do you really think Katy will be touring and preforming songs like calforina girl and teenage dream when she's in her 40's she needs a complete sound overhaul

Obviously. Not to mention other flop songs from Nick Jonas and these Australian singers.

Ask Nick, Nicki and Iggy

Right, let me add Nick's song to the OP

Yes, definitely

Found more.
