It's a musical edition of the daily Speak-Up on Kotaku today, as commenter Harrier entertains us with more than 25 minutes of Mario piano music, played nonstop and without the aid of sheet music.

My 25-minute-long medley of songs from various games featuring Super Mario! It isn't perfect, but it's kind of tough to go for so long without breaks - especially considering this is all from my head... I'm not about to try transcribing all of it down onto paper, especially since it's all just played by memory / ear :P

About Speak-Up on Kotaku: Our readers have a lot to say, and sometimes what they have to say has nothing to do with the stories we run. That's why we have that little forum on Kotaku called Speak-Up. That's the place to post anecdotes, photos, game tips and hints, and anything you want to share with Kotaku at large. Every weekday we'll pull one of the best Speak-Up posts we can find and highlight it here.
