What's funny is that this song would be just fine if it was Kiiara feat. Linkin Park.
But that's not what it is. I wasn't really sure what to expect because I hadn't paid very much attention, but I certainly didn't expect a straightforward pop track. I don't know how I feel about it. I think, as a song, it's fine. Chester's vocal performance is interesting, but I don't think his voice is suited to the style he's trying out. I think he needs to have a harder edge to his vocals for them to sound good, and this performance is a little too airy.
It's a catchy song, and I think it could gain traction on pop radio, if people get past the idea that it's a Linkin Park song and don't have an automatic "ew the nu-metal band" recoil. Who knows.
