Try Jukebox, that allows for playlists, as does MPlayer, SongPlayer, there's also SoundBankster (DJ'ing really but will load/play mp3s), AminetRadio, all come with MorphOS, or there are other, and some older supported players such as DigiRoller, DigiBooster, even GoatTracker, ExciterPlayer, for modules, and don't forget to try some of the older Amiga Classic players as many of them work with MorphOS as well. Loads of choice . . ENJOY
