Exclude a playlists tracks from personal mixes

Feature description:

I have a some playlists (smart and manual) that are holiday themed e.g. Christmas and I do not want those songs included in mixes. Short of removing the tracks from the media provider there is no simple way of excluding them. E.g. multi select tracks from a playlist then exclude is also not possible.

Problem solved:

Solves needing to skip and increasing skip counts unnecessarily and apologising to people when one of these songs starts playing in a mix.

Brought benefits:

Better curation of music.

Other application solutions:
