Do you listen a lot of music but you have so many songs that you often press next?
Solve it by making a playlist and then you can open this with your standard mediaplayer!
Make with this app quick and easy playlists of certain directories and names(filename title artist album genre). With convenient sorting and check functions!
There is also the possibility to use this as a media player! Although this is mainly for recognizing songs.

New runner up app but care still in alpha! Alpha link:
