I am currently working on a new single called "All Because of You", and in the second verse, I use some of utada's lyrics, japanese ones. I took 3 sentances from 3 different songs, and a sentance I composed. The sentances do not have the same melodies as the originals. So it sounds NOTHING like Hikki. But I am wondering is this considered plegerism?

Here are the lyrics,

koi wo shite subete sasage (falling in love, giving it all)(from Sakura Drops)
yume miteta no wa doko made (How long have I been dreaming?)(From Be My Last)
ki ni naru noni kikenai (I'm anxious, but can't say anything) (From Final Distance)
Nani wo warai? Nani wo Warai?(What are you snearing at?)

Thank you for your responses. :)
