Ayu songs you can sing well?

[gallowsCalibrator]

What Ayu song(s) can you sing especially well? Without problems of pitch or your voice cracking?

For me, I do the best with ballads and fast songs... They're the opposite, but I have the least problems with them

The songs best for me are evolution, teddy bear, JEWEL, Free & Easy, part of Me, momentum, and HEAVEN (^_^)

I have a lot of fun singing them and I feel that my voice isn't too awful for them (that's just me though O_O)
