This is used to notify when tracks have been played so dynamic playlists can be updated, and so the model can display the correct playcount. The old system playlist tests are mostly unnecessary at this point, so I remove them as part of this patch. Signed-off-by: Anna Schumaker <Anna@NoWheyCreamery.com>
