i thought so too, i mean, it was gotten out rather early that she was a good singer, hinted it may be her true talent, and everyone is pretty bad at doing something when they are tired, for instance, i am a good writer (i think?) but if i am tired all i can put out is pure and utter garbage, so i would chalk up to her singing in 'sleepless in ponyville' as sleep deprivation
Ah I see, older generation. I wasn't into MLP since before this summer so I wouldn't know. I would have thought of a bell ringing, but then I am not an artist so it wouldn't look like a bell anyway. Anywho, keep up the good work!
