My Question or Issue

Whilst transferring my sons music to Spotify from Apple Music using Tunemymusic it somehow got transferred to my library instead of his (there was no option to choose which Spotify account to add it to). I've not had any help from the Tunemymusic support but is there any way to quickly edit albums and playlists in Spotify rather than going through the whole library doing it one by one? Thanks.
