John,

As I always say to these requests for recommendations:

- who is the target audience (background/geography/age/tastes)?
- what kind of material do they seem to appreciate?
- any chance of asking the suggester for some specific artists?

I’m not sure how useful Ian’s billboard listing is.
Taking just the top 20, I count 6 funk or cod funk tracks, 1 country, 3 pure pop, 7 soul/ballads and just 3 that could loosely be described as rock (and they include Maggie May!)

I thus offer you an alternative rock list:
