It's OK, but I think Someone Like You would suit the 4 AM remix better.
The momentum builds up until 0:55 and it just.. dies. The acapella is far too powerful for such a subtle beat, imo.
Yes, very true. The keys are different, so it's basically just the Adele vocal over a drumbeat for the first chorus until the Kaskade synth kicks in to carry out the rest of the track. I was intrigued by the instrumental because it really showcases & allows Adele's vocal to soar
