I heard spcialist's Hero in Training, which is an epicly awesome song.
But I just really felt like making my own version, so I got permission to make one!
I tried to make it close to the old version, but I changed some notes, and added some whole new parts.
I had to cut the end of the song to make it under 8MB, so I just made it loop instead :)

Make sure to check the original out too! :

And of course check out some of spcialists other songs. They're great.
