This is the catchy background music for the montage where the Cutie Mark Crusaders attempt to brute-force their way to getting their cutie marks.

There is another version of this here on YT but it still has all the sound effects in it. This time, the instrumental music was ripped by Senn555 with no sound effects - thanks!! (There are still a few sound effects that are impossible to remove due to the way they're embedded in the audio, but they're like 99% gone)

Do you want an official MLP:FiM original soundtrack release? Hasbro will likely only consider it if they see the support (and therefore potential sales) for an OST release. So sign the petition! (and if they do release it you better buy it - Pinkie Pie is watching - ALWAYS watching)

The more fan support, the better the chance of it happening!
