Zelda III Dark Overworld
Cave Story Theme Song (Curly)
The BRSTMs actually sound a little better than the Youtube videos, since they were recorded more recently (last night! xD) and with slightly better instruments.
Please enjoy, and let me know if you have any comments.
I will continue to make songs and I'll put them on this thread.
