I actually liked the songs more than the one in "Bats!". Like, a lot more. Even though some of the rhyming schemes seemed weird. (Well, except the musical's one line. Ironically, that just seemed painful. Wonder what my opinion would've been with context?)
Honestly, Manehattan seems so wildly different from Ponyville, Canterlot, Appleoosa, Dodge Ranch, the Crystal Empire, etc. that it's... weird. Like, the first two and the last are still vaguely medieval in nature (just... with arcade machines and sofas), the other two are full-on wild west, and here we have practically modern urban. All over the place. Don't take that as a total pejorative, though, because I actually love this urban setting. I hope we see more of it, anachronistic or not.
