How do I get rid of music / songs from my Apple Watch, that shouldn’t even be there?

Good day to you Brett Archibald, 

We’d like to have you remove that one playlist and see if that removes all the Music data or if it remains the same. Remove music from Apple Watch

Remove music using your iPhone

1. Open the Apple Watch app on your iPhone.

2. Tap My Watch, tap Music, then do any of the following:

• For music you’ve added: Tap Edit, then tap next to the items you want to remove.

• For music that was automatically added: Turn off Recent Music or other music automatically added to your Apple Watch.

Note: Music you’ve recently played won’t be automatically added to Apple Watch until you turn on Recent Music again.

Music you remove from your Apple Watch remains on your iPhone.

Remove music using your Apple Watch

If you’re an Apple Music subscriber, you can remove music directly on Apple Watch, whether it was added automatically or you chose to add it.

1. Open the Music app on your Apple Watch.

2. Tap Library, scroll down, tap Downloaded, then tap Playlists or Albums.

3. Swipe left on a playlist or album, tap the three ellipses, then tap Remove.

4. Tap Delete.

The music is removed from your Apple Watch and from all other devices that use the same Apple ID.

Note: You can also remove individual songs. If you swipe left on a song, tap the three ellipses, tap Remove, then tap Delete, the song is removed from your Apple Watch and from all other devices that use the same Apple ID.

Thanks.
