The official MLP YouTube channel just posted a Tricks Up My Sleeve music video, sung by best pony/human.
The video is basically a collection of Trixie clips from EQG and EQG: Rainbow Rocks, but for those interested in hearing the full uninterrupted song from Rainbow Rocks: the video can be found here or below the break.
(Side note: Trixie not actually best pony. Please don't fire me, Seth)
