To add music you can press Ctrl+O, the Load some music button or the + button and select the folder where you store your music files. To play the file(s) select it and double click on it or click on the play button.
Current music players are focused on managing your music collection, while using mandatory criteria about how they organize it.
Eina does not care about it at all. If your are an organized person, chances are your music collection is organized too, and you won’t like to spend your time rearranging it to follow your player’s specific rules. In addition, having those players to arrange music that’s randomly stored, named or tagged, is usually counterproductive.
