Too much Metroid! :P
You've done some pretty nice work here
Okay... Heard through 31-40, and only liked 2 songs really. (OoT one and Starfox one).
The other ones are good, but I'd rather just listen to a random song (metroid disabled) on the Brawl soundtrack.
41-50: Very good, but too much metroid (again).
Love the Kid Icarus & Pokemon Blue one (never was too good with the names of the songs)
Hmm.. Btw! You should have the red screen saying which song it is up later... I love having an image (/video) in my head of where I was in the game.
Love the SMG one too :D Too bad it was followed by Metroid.
Pure genious OoT (Gerudo Valley). Glad you added that one so high up, as I feel it oftenly gets ignored. Too bad it was followed by Metroid
51-60
Kirby 
And liked the SMG and Pokemon one
But THREE metroids? :/
