This is a great track. Very subtle and laid back, excellent to chill to. Interestingly enough, Shinobi is not where I have heard this melody before. There was another game out for the Sega Master System called "Alex Kidd in Shinobi World". I don't know if the same composer did music for both, but the track remixed here is the same as the inbetween level music for that game. Upon further research, many tracks are the same from both games. Including the boss theme, beating a level theme, and the dying theme.
