James Pond: Underwater Agent (1990)
I've long felt alone in having a soft-spot for the first James Pond game. Many love its sequel, Robocod, and justifiably so, but the original? There are many things I like about it - the jolly graphics, the environmental theme, the fact that it takes place underwater (well, James is a fish and all) - but one of its less appreciated features as far as I can tell is its music, composed by Richard Joseph. Much of it is somewhat more befitting the character's secret agent status but my favourite is this, one of two level themes that get alternated. It's might be a little strange but it suits the game well and also makes me smile every time I hear it. What more can you ask for?

Special Note: I didn't record this great tune myself, I'm just an admirer, so all credit to, firstly the original composer, and secondly the YouTube user who uploaded it!
