Gm3u is a playlist editor for MP3 files created using the GNOME libraries and GTK+ toolkit.
What's great about Gm3u is that playlists are stored as text files, making it easy for MP3 players to use them. Simply select MP3 files in the file browser and add them to either an existing playlist or create a new one from scratch.
In addition to adding songs, you can also remove them, move them up or down the playlist, move them to the end or beginning of the playlist, and more. Plus, if available, the ID3 tag of the MP3 file will be displayed when you select the file.
One particularly handy feature is the ability to play single songs with an external MP3 player. All in all, if you're in need of a reliable and easy-to-use MP3 playlist editor, give Gm3u a try!
