I used LMMS.
"Who forgot that Twilight Sparkle had a laboratory under her library?
Not I.
This was heavily inspired by that lab, and what's strange is that the title came to me before I thought about its relevancy to Feeling Pinkie Keen.
That's what she's trying to do, right?
Figure out, amongst all other strange phenomena that course through Pinkie Pie, how exactly she is able to sense the future?"
The verse endings are not parallel and the two last segments at the final chorus could be taken out (or perhaps just the third), also, upon further listening I discovered that a few smaller sections would benefit from having the drums taken out (for a short time).
But that's enough from me; I'd like to hear what you have to say.
Hope you guys like it.
