For the past two years, at least once a day, my friend meesh and I would break out into "I'll Make A Man Out Of You."
I love the Glee covers, usually more than the originals. Well, it depends. I'm not a big fan of Barbra's voice, so Rachel's covers are love. Actually... basically, I love Chris Colfer and Lea Michele's voices, and will take their cover over any originals. And between them, that's most of the Glee songs.
Secondly, I own all of the Glee CDs, so it's way easier to use the Glee cover than to buy the original.
Also, I learned today that I am an... aural and kinesthetic leaner. Equally. I like shtuff.
