I actually wrote a song in the 2017 February Album Writing Month challenge asking this question as the premise of the song. Intentionally copped the style from a conglomeration of bands that I like and even tried to mimic the zero vibrato nasal tone of one of the lead singers.

Participation in that challenge might help you get out of a rut and try something not typical for you. Tons of prompts and games and collaboration opportunities.

Several PG Music forum participants have joined in over the years.
