GBA games were generally regarded as having lower sound quality than SNES games, although this perception was somewhat exaggerated by the poor quality of some SNES->GBA ports. It took a lot more CPU to get good audio out of the GBA, and I'm sure developers were taking the GBA's tinny speaker into account when deciding how much effort to invest in polishing the soundtrack. Hell, the GBA SP needed an adapter to use headphones!
