Some kinda conundrum

Things regarding release may slow down slightly. I've got plenty of ideas, but the big question always ends up being "What do I wanna do next?" And that question is sometimes hard to answer. I've had to displace a chapter that I've got planned because it's gotten a bit difficult on the mental front to write. I feel like if I don't have some kind of musical number fitting for a certain situation, I would be doing the character that is brought forth into the chapter justice. But the situation I have is one that would demand an original number, rather than something previously written. Sad fact is, I'm terrible at writing lyrics. I can write prose, I can write poetry, but coming up with something original for a song in both words and accompaniment is... a little bit beyond me. Despite what I may have written so far, I can't actually read music, nor can I identify a note upon hearing it. I'm mostly vocals and percussion. Not much music reading there in a lot of cases, especially when you're mostly self-taught like I am. However, I still want to do this character justice by having something that fits his personality. So, I'm putting out a request. If you or someone you know can write a good tune, send me a private message! I'll give you the full rundown as to what's going on, and a sneak peek of the chapter in question, and we'll see what we can do.
For a very basic gist of what I'm going for, here's what it is on a very base level. Also, future chapter spoilers ahead.

I need to have a duet for Pinkie Pie and Cheese Sandwich. The party ponies partner up!
