Opus 1 Music Player

Feature enhanced sibling of the "Unpopular Music Player"
Instead of "Artists" and "Songs" in pop(ular) music, this program uses the metadata composer and grouping to organise the music in works (e.g. a symphony) consisting of movements (parts of this work).

Further, no text is truncated, i.e. long movement names or performer lists will take as much space on the screen as they need to be visible in full length.

This application might be seen as an advanced version of the Unpopular Music Player, with added music database query functionality and further enhancements.

The program can work together with the Classical Music Tagger and the Classical Music Scanner.
