Super Mario RPG, Super Mario 64
Bowser Medley was my first stab at a Bowser song.
Bowser is one of my favorite VG characters, and he is always surrounded by awesome themes. Here we have his fight music that appears in the first part of Super Mario RPG, followed by his normal and final battle music from Super Mario 64.
Although far from the most popular of the 2009 songs, I get asked about this one occasionally, namely the Ultimate Koopa part. I actually still use Ultimate Koopa as one of my warmup exercises on guitar. I may remake this one in the future, so keep an eye out for it.
