Is my daughter gifted?

The other night Michaella and I were watching Dance War...she loves it. She loves to sing and dance. She is most often making up her own songs. On TV they were doing a recap of the season. They gave about 5 seconds of a song that was done the first episode 5 weeks earlier and then moved on to another song. Michaella continued to sing that first song. I know for certain she has only heard this song ONCE 5 weeks earlier! This is not the first time she has done this. She will hear a song and she will be able to even tell you who she heard it with. They are Mommy's songs or Daddy's songs. Michael listens to some non popular songs (I call them wierd and annoying he calls them music ) it's nothing you would hear on the radio. And she is able to recite lines from them after only hearing it once. Is this normal? She seems about the same skill level as all the other kids at both dance lessons and tumbling. The only difference I see there is that she has no inhibitions and no stage fright. Kaella has also been coloring in the lines for 6 months. At her 3 year appointment she was able to draw a square which the Dr said was a 4 year old skill. Are these signs of her being gifted? Anyone else with kids her age have any thoughts....please?
