I wouldn't be so sure. I doubt that a 16.77 MHz ARM7TDMI
processor can decode 44 kHz stereo MP3 audio in real time.

And it would have to have its own headphone out, even if it were
GBA specific. Each channel of MP3 audio is normally decoded to a
16 bit per sample buffer. GBA sound is 8 bits per sample. They'd
have to do a lot of noise-shaping to push all the noise up into the
high frequencies.
