Importance: Low
Launchpad Issue: lp1845837
Tags: library

When purging tracks Mixxx tries to delete those tracks from every playlist.

The only playlists I have are history playlists, many. Purging tracks from each playlist invokes PlaylistTableModel::select() for each processed playlist which could be slow for a big library. As a consequence, the UI is stalled for minutes!!

This bug is caused by invoking PlaylistDAO::removeTracksFromPlaylist() in a loop in PlaylistDAO::removeTracksFromPlaylists(). Each emitted changed(playlistId) signal triggers a PlaylistTableModel::select() operation.
