I've never been a huge fan of the songs in MLP, so this would have been a totally forgettable episode if it hadn't been for... well, you know.
Sorta came completely out of nowhere, didn't it? This was definitely one of those episodes aimed squarely at the target audience.
As far as the fandom's creative side is concerned, it's probably a good thing that they explained absolutely nothing about Twilight's new role. Gives lots of scope for making stuff up.
However, it's a bit frustrating that we're going to have to wait until season four to find out how the show will be affected by this.
I'll be starting a new multi-part story in March, btw. It'll be a short little thing with Berry Punch as the main character, though it'll have nothing to do with Spyra. Bon Bon will be a part of it too. Stay tuned.
