Use the most popular artist if the song has multiple artists

Help

How would i check my library and select the artist that appears the most for songs with multiple artists? Say, i have 10 songs from artist A, and i get a song with artists A and B, i want to select artist A as it’s the most common in my library.

Ended up writing a plugin for that, was the quickest way to fix this issue

from beets.plugins import BeetsPlugin
from beets.ui import Subcommand

modify_artists = Subcommand("multipleartists", help="Fix artists")


def modify(lib, opts, args):
    all_artists = {}
    for item in lib.items():
        for artist in item.artists:
            if artist in all_artists:
                all_artists[artist] += 1
            else:
                all_artists[artist] = 1
    for item in lib.items():
        if not item.artists:
            continue
        counter = {}
        for artist in item.artists:
            if artist in all_artists:
                counter[artist] = all_artists[artist]
            else:
                counter[artist] = 1
        artist = max(counter, key=counter.get)
        print(f"Modifying {item}, setting artist as {artist}")
        item.artist = artist
        item.albumartist = artist
        item.store()
        item.write()


modify_artists.func = modify


class MultipleArtists(BeetsPlugin):
    def commands(self):
        return [modify_artists]

Beware, this code has no confirmation or anything (nor is it great), its just for my personal use. Modify if you want to add confirmations/other stuff.
