How to "replace" my own music for Spotify music ?

[ValentinLauLau]

Hello guys,

I'm new on spotify and I need some help. I add to my spotify my old library (around 1400 songs) and i would like to "replace" them for the one of Spotify because metadatas are wrong. For example, I have "Harder, Better, Faster, Stronger" from Daft Punk but the name of the song of my old library is wrong and there is not the artist. I would like a clean library. I don't want to add 1400songs by myself 😕

Thanks
