Around half of every GBA game on Vizzed now has a soundtrack uploaded for it in the Video Game Music feature on Vizzed:

(click the 'Game Boy Advance' drop down to view them all)

The reason it's only around half of all GBA games is because there's so many GBA games out there and I don't think there are enough resources out there to obtain full soundtracks for every GBA game without manually ripping them which would be far too time consuming to justify doing.

About 750 soundtracks were uploaded to the Game Boy Advance but most of the most popular games were taken care of. It'd be great if you guys could help rate various GBA songs so that the following GBA playlist shows the best songs for the system:

Thanks to Juliaisme123 again for helping me out with this project. I'm not sure which system I'll be doing next but I'll probably take a little break from focusing on individual systems for a while.

Davideo7 : Ah another one of my favourite game systems I had a ton of gaming memories on the GBA and I loved pretty much all the games that were released on it. So I can't wait to start looking through all the songs that I can remember listening to!

Nice, the GBA, had some of the best video games for songs that I like, so once I get a chance, ill probably take some time to listen to dozens of songs. Of all the systems that could be added for music, I probably say that this one would be one of the ones that I would like the most.
