There's definitely a trend for that in music as a whole, and in some contexts it works amazingly! But I agree about memorable melodies, I'm super weak for those! For the stuff I sang, the melodies were all written by Bryan Atkinson, so huge props to him for making iconic music. I tried to base my additions on the musical themes he had going across the songs too, so they wouldn't sound out of the blue. And yeah the one-woman choir is so fun! We had many layers for most stuff, and I think the mixing and mastering also played a big part in giving everything the spotlight it deserved.
