Samples in Ayu’s music used by her and other artists

[MKAyu]

I was surprised to learn how much of (Miss)Understood was covered Sweetbox music (my fiance and I got into an argument because he insisted Bold and Delicious was a cover, but I didn't think Ayu had covered anything on (Miss)Understood).

That's not sampling, exactly. I think technically "Bold and Delicious," "Ladies Night," "In the Corner," "Pride," "Beautiful Day," and "Rainy Day" are covers? But the lyrics are Ayu's own, so that's not usually what you'd call a cover . . . is that sampling when it's the entire song?
