I have a Nokia N-Gage QD, and I got an mp3 program for it (from www.lonelycatgames.com) and it also supports those file types for audio, and they are really low in file size, so I was hoping I could get some music tracks like that and store more songs on to the memory card. Ive had a bash, but i get a distorted buzz for about 5 seconds of the song, and the rest is silent.
