Corazón Espinado. Whenever Carlos is playing, it's a solid 98. Everywhere else, to my ear it's a 60--decent South American pop. Split the difference: 79

Smooth

I've always liked Smooth. It's a great Santana song throughout (especially if you karaoke out Rob Thomas, who I've always thought was a lesser day Mac Davis--which means I never cared for him). 90 (a genius at work; with better vocals, maybe a 96)

I didn't know Corazon--thanks for the discovery.
