> I mainly like it for their folder organization
If you don't like Amarok or Clementine, the following are available in Muon Discover, under Multimedia:
JaJuk - http://jajuk.info/index.php/Main_Page
> Jajuk is software that organizes and plays music. It is a full-featured application geared towards advanced users with large or scattered music collections. Using multiple perspectives, the software is designed to be intuitive and provide different visions of your collection.
Tomahawk - http://www.tomahawk-player.org/
> Tomahawk is a music player that fundamentally changes the way music is consumed and shared. It decouples the name of the song from the source it was shared from - and fulfills the request using all of your available sources. This creates a universal translation layer across music repositories, streaming services and geographic territories.
Bangarang - http://bangarangkde.wordpress.com/
> Bangarang is designed for your KDE powered desktop. Fully integrated with KDE’s Nepomuk semantic desktop, Bangarang has access to indexed media information and automatically shares its own media information, rating, tags and usage statistics with other KDE powered applications. Anything Phonon plays, Bangarang plays. Audio settings and video settings are automatically enabled if the Phonon backend supports it.
Jajuk, especially for its 'folder view' to me, as it respects how albums are stored in the hdd and displays structure accordingly.
Java, but works well.
