This is how music players should be.
So simple to use, to choose and add music to a playlist, to control, etc., without all the confusion and bloat of these "modern" music players that attempt to manage your collection for you.
What an insult to the intelligence those players are. As if the user isn't smart enough to organize their music files in a heirarchical directory structure by genre, artist, album, or something.
Don't manage my music, just play it!
That's what MOCP does.
I LOVE IT!
