A few months ago, YouTube song artist Grant Woolard mashed up tunes by 33 classical composers—including Mozart, Tchaikovsky, and Beethoven—into one 6-minute piece. Slate recently posted the final product: a surprisingly catchy melody that pays homage to the masters while still providing your ears with something new and fun to enjoy. Listen to the tune above and see how many individual artists you can identify. Also, check out Woolard’s YouTube channel for even more unexpected song combinations, including a mix of 49 Disney songs and an auto-tuned "Hallelujah Chorus" from Handel's Messiah.
