Heard a song in Market Basket and I have no idea what it is?

There is a song i hear in Market Basket all the time. I clearly have
the lyrics wrong because i cannot find it anywhere on the internet and
was hoping someone may know what i am describing.
The song is sung by a young woman with an amazing voice. The entire
song is set to a piano (it may have some string instruments as well)
and kind of an indie style sound. The lyrics i think i remember are:
"Oh oh oh oh oh oh oh i dont wanna be whoa oh oh..." then the song has
a very...circus-like beat as the singer lists things off saying AND
between everything like "Six and Seven and..."
The song itself is VERY CATCHY and repetative, but it has gotten stuck
in my head and i have found myself standing in the aisle bouncing to
the song on more than one occasion. i hope this is enough to get help
=(
