Today's #TuneTuesday theme is #SteppingStonesSongs (or #SteppingStoneSongs) - songs that introduce you to a specific (sub(sub(sub)))genre of music.
This will require a bit more thought than "throwing something up right before I head to work" so to start, I will toss out for #AniSong specifically--anime theme songs, which are usually their own takes within and around #JPop or #JRock or otherwise.
And the one that looms largest for me is "Konya we Hurricane"
from Bubblegum Crisis (1987) - by Kinuko Oomori
It does a marvelous job linking "the MTV Generation" to anime, including titillation and action and sci-fi horror aspects in the opening scenes of BGC, and a fully 80's-captured style in the music video.
