Quick and Easy Translation for a Song Lyric?

I am trying to write a song in Japanese.
To say, he is not an utau, would be UTAU dewa arimasen, right?
Then, how do you say, He has no voice, but I love him anyways?

:) I know limited Japanese.
Thank you!!

Do you want to say "he is not an utau"?
"utau" is a verb "to sing," so it is out of place...

Also what kind of tone (casual, polite, female/male, etc.) do you want?
That really changes the whole sentece...

He has no voice, you mean his voice lacks volume, or he cannot sing?

UTAU is a thing similar to vocaloid. The song is from a girl to a boy. The boy has no voice what so ever, so he cannot speak. If it helps you, his name is Sosuke. I really need help with this! I don't know much japanese yet. -.-"

Watashi wa baka desu...

Thank you very much!
