I'd almost swear that nearly every Viz Media tape I watched had this song advertising the 1st Ranma movie, Big Trouble in Nekonron, China.
It's Love - ED
Which, it was definitely used on every single Ranma tape. Of which, I have the dub tapes, thus, I grew up watching Ranma dubbed. So, there's this from the OVA series.
Love Panic! - OP1
Been a morning of strolling down Nostalgia Lane.
I love this so much for the same reasons. Ranma 1/2 was my first ever 'independently sourced' anime (i.e. one of the only VHS anime available at my local video rental as a kid, so I rented them out every opportunity I had). So many memories.
In terms of mine, I used to skip the openings and endings, but then I heard the opening for Rainbow: Nisha Rokubou no Shichinin. I stopped skipping. I now have a policy of 'at least one listen' for each. Now I have a steadily growing list, and my music taste can be a bit fussy/niche.
Obvious Honourable Mention to the entire soundtrack to Berserk
