Spotify plays a different song on my mac than on my iPhone (same band and songs, old and new singer)

[Haelx]

Hello there, I wasn't sure if I should post here or in the mac category, but I figured either is okay. Here's my issue :

My favorite band, Rhapsody of Fire, recently changed singers and released an album of re-recorded songs from older albums to give us a taste of what the new guy can do. The songs are all named "old song name - re-recorded", and the album is "Legendary Years - re-recorded". Furthermore, the old songs are separated under two diferend band names (Rhapsody, then Rhapsody of Fire, they had copyright issues years gao and added "of fire" to their name. I do have all the old songs on my mac, but not on my iPhone, and theses issues affect songs from both "rhapsody" and "rhapsody of fire" (tho I think the band name on my mac iTunes is always Rhapsody of Fire, unlike on Spotify). When I play this album on my mac, it's the voice of the old singer, but on my iPhone it's the new guy. It's very noticeable and weird, do you know how I can fix it ? I guess it has to do with me having the old songs songs imported into Spotify, but they don't have the exact same name (the "re-recorded" part) so it's weird. Anyway, any help is welcome, I hope my explanation wasn't too complcated 😕

Thanks !
