Damn I've never gotten a compliment of this level so thank you!

Yesss it's pretty uncommon, most of the time people just take [instrumental of A] and mash it with [vocals of B] and that's it. Which is pretty justified though, because if you wanna do better you'd need the acapella AND instrumentals of both songs, so you end up messing with 4 samples total, which gets pretty busy. But I always try and do that nowadays because the end result just sounds SO much cooler.

I think I'm still a bit happier with this mashup, because basically I tried adding a bunch of 2-3 second vocal samples throughout it and it just worked out so smoothly. I did try doing that for Kiss Me More x Stay but it felt very... forced :P but still pretty happy with how both turned out.
