Steps to reproduce the bug

1. have multiple audio files with the same Album tag but different Artist tags
2. go to the Artists tab

Expected behavior

• the Artists tab should contain a list of all artists of all audio files
• when viewing the pieces on one particular artist the list should contain all audio files that contain that artist in any of their Artist tags and no other files

Actual behavior

For every album, all pieces in the album are assigned to a single artists. This means that the Artists tab does not list some of the artists of albums with multiple artists and the piece list of an artist can contain pieces that are not played by that artist.

It should be partially solved after adding support for album artists in #51. However, I leave this bug request in case that this feature wouldn't address the issue of assigning track artists wrongly.
