So, this happened:
I personally think “Rolling in the Deep” is one of those songs that it doesn’t matter who covers it, the original is always going to be best. It just sounds like Aretha Franklin is having a bit too much fun with Adele’s song. The original song is about intense heartbreak and anger at a spurned lover, so singing “ain’t no mountain high enough” (starts at 2:45) and doing those vocal runs just doesn’t make sense. It almost sounds like Aretha is celebrating something…but really, “Rolling in the Deep” is not something you play to rejoice and celebrate; it’s something you blare when you’re pissed off at someone or hurt deeply.
I’m not saying Aretha’s version is awful, it’s just different. I actually thought it was pretty fun to listen to.
