[BUG] Artists on a track should be comma separated

[MrPatben8]

Describe the bug
Tracks produced by multiple artists (especially in more contemporary music) typically has all artists listed in the artist tag, separated by a comma for each attributed artist. Audioplayer should evaluate each track's listed artists and group tracks correctly by individual artist rather than collaborations. I've attached an example that clearly illustrates this issue.

To Reproduce
Steps to reproduce the behavior:

1. Sort library by "Artists"

Expected behavior
A song with two or more artists in the "artist" tag should be attributed to multiple artists. For example a song that is tagged as "artist: Deadmau5, Grabbitz" should generate two artists "Deadmau5" and "Grabbitz" rather than one artist called "Deadmau5, Grabbitz".
