Groovy sometimes gets pretty annoying after listening to it for several times...
I chose honey since it has a soothing melody and good for singing-along.
Fruits and Candy would be my second choice...but the artist was sang it in a pretty loud strong voice...so it sometimes wrecked my eardrums....lol. no offense. Ohh...if u guys really wanna try listening to fruits and candy I would strongly prefer the Sakura, Tomoyo and Kero version...its pretty good.
