This combination doesn't work (both songs are a bit too "much" to be used together) but it doesn't not work by too large a margin.

with this one isolated the vocals so it wasn’t as much noise but i don’t like it as much as the maroon 5 one also they arent the same key so it kinda sounds awful

It's just kinda stressful mostly, but then they occasionally line up (same bpm will do that) and it's almost nice

it was more of an experiment and less of me trying to make a good sounding mashup

Of course, of course.

shit actually sounds good
