I am loving the chord progressions at the verses. It just oozes nostalgia from my childhood. Also, I'm finally old enough to get some of the lyrical references to that time period like "cross my heart and hope to die" being straight from 2012's One More Night!
I just have a few general concerns. Firstly, Andrew kinda hit the nail on the head mixing wise, as it can be hard at times to hear the drums during the choruses. Maybe this is just me but I think the lyrics at these parts are just a little bit cheesy and generic. More melodies would be nice in general, maybe somehow incorporating this hypothetical B melody into the second chorus to bring some variety to the second half of the song. I also think the chords at the choruses are, like the lyrics, ultimately pretty bland and generic, which was probably done to match the time period (I'm thinking OMFG and LMFAO here) but there comes a point where you dont want to repeat the same mistakes early 2010s music made for the sake of the theme! I already think the verses pay homage enough.
Despite all this, the emotional beats of the song resonated enough to make this song shine, and I'm looking forward to see what you have in store!
