For me, a recent example would be Fiona Bevan, co-writer on the Backstreet Boys’ recent hit song “Chances”. I had never heard of her, but am now aware of her and will be keeping an eye on what she releases next.
First off, I want to preface this by saying that any musician that tells you a song is only good if it’s lyrics are deep, or a song is always bad if it’s lyrics are simple, is wrong. Music is a matter of taste. I love pop music, always have, and some of the best written and catchiest pop songs are incredibly simple lyrically. That doesn’t mean they were easy to write though. Pop is an art form just like jazz, ragtime, classical, soul, R&B, etc. In fact the roots of pop come from jazz.
