Will we get more Ponytones Episodes?

[BrawnyCharger 513]

Filly Vanilli introduced us to the Ponytones, a quartet (now quintet) consisting of Big Macintosh, Rarity and now Fluttershy along with two other ponies. 

Since that episode, one wonders if the group would make a return in any future episodes. After all, three of them are established regular characters. It would make for some great interaction moments, (and a shipping moment or two). It would also provide character development for the two background ponies. 

What sort of new episodes can work for the Ponytones?

Maybe there might be a particular event that would consist of them, but I don't see another full episode dedicated to them.

I would like to see them return, if only for Fluttershy to be given something to do.

Maybe they'd sing a new song, and possibly release an album. This could lead to them getting noticed.

I definitely would not mind it. It is an area of music that simply isn't explored very often in any kind of show so it needs more love. Let alone giving Big Mac more screentime. Not sure what the plot would be though in this case.

I hope they return in S7.

Maybe another pony would want to join. Either an established pony or a new character.
