eTunes

eTunes is a small free program that allows you to organize your music without hassle. eTunes loads a list of your files in a folder you specify and you can search, rename, delete, and edit the ID3 tags of your files. Or you can let eTunes show you random song(s). Once you've decided what you want to listen to just click play and eTunes sends the song to your default media player. Unlike similar programs eTunes doesn't hog your resources or prevent your from using your favorite music player.
