I am producing/engineering an EP for an artist, Saeyers. We have been releasing songs from the EP as singles as we wrap up the EP.
Our first song, Cruise, drew over 30,000 plays, and was added to Fresh Finds for two weeks. The problem is, as we have been wrapping up the other songs, we've found that Cruise is much louder than our other songs (we mastered it too loud, in comparison).
I would like to remaster the single so that it better matches the other tracks (bring the volume down a couple decibles, and adjust a specific frequency range).
If I do this, will Spotify recognize the song as the same song? Or will the playcount on the EP start at zero? Is this determined by the ISRC and other codes for the song?
Or do we need to release the song as is to retain the play count?
