There's an app called songshift but I've never used it, and there's also this website that I have used before.
I would suggest finding some international radio streaming apps. I use this app for finding new Japanese music. There are so many stations you can find whatever you want. I have a similar one based in Israel, no doubt you can find one from Spain
This is the album type you're looking for
https://www.amazon.com/Best-80s-Dance-Vol-Remixed/dp/B07CBN1SYX
There are several volumes of those for you to check out too. They're dance remixes of 80s hits.
It's been ears that I've been in love with this song, and a couple more from this series, I hadn't heard anything like it, and man, something about it is just perfect.
I got recommended Memphis exorcism by the squirrel nut zippers, which is pretty good too, but the sound of the trumpets in this is just stunning, and I've always craved more.
Edit: here's the other one, just on a file sharing site since I couldn't find a streaming version anywhere. Again, it's the trumpet that really stands out, but the rest of the song is just fantastic too. http://www.filedropper.com/03juveniledelinquency
Music can enchant minds, heal sickness, destroy castles, summon creatures, discover knowledge, peer into the darkness, tame tempests, repel fire, even transform the landscape.
Listen to the music from the Potion Voyages...
Magic Music From the Potion Voyages Book Series (Soundcloud)
Yeah I know what you mean, classic is a kinda contextual category but hey I still use the word, like I would to describe this other new orleans 'classic' Cissy Strut by the meters... never before has funk felt so classic, really worth checking out (especially the josie recordings) - https://www.youtube.com/watch?v=4_iC0MyIykM
https://www.discogs.com/Various-Atlantic-Gold-75-Soul-Classics-From-The-Atlantic-Vaults/release/602680 here is a great compilation of soul classics its worth a dig around there are some bangers, shame the comp isn't on youtube but theres a list of names, again there is much more
