A rock song FFVII: AC idea

I found this song on the American Idol Season 5: Encores CD. This song was originally done by the rock band Heart, but on the AI CD, it was done by Melissa McGhee. I say that perhaps Tifa can perform this song, because what Cloud is doing is captured in this song. Perhaps her singing voice in Japanese could be Ayumi Ito, considering that she was the lead singer of the rock band Mean Machine. In English, her singing voice could either be provided by Rachael Leigh Cook (if she can sing, which I think she did in Josie and the Pussycats) or Katharine McPhee. Considering those facts, I thought that Tifa could be a rocker chick, just like her voice actresses. Here are the song lyrics:

What About Love
Heart
(Heart)

I've been lonely
I've been waiting for you
I'm pretending and that's all I can do
The love I'm sending
Ain't making it through to your heart
You've been hiding, never letting it show
Always trying to keep it under control
You got it down and you're well
On the way to the top
But there's something that you forgot

What about love
Don't you want someone to care about you
What about love
Don't let it slip away
What about love
I only want to share it with you
You might need it someday

I can't tell you what you're feeling inside
I can't sell you what you don't want to buy
Something's missing and you got to
Look back on your life
You know something here just ain't right

What about love
Don't you want someone to care about you
What about love
Don't let it slip away
What about love
I only want to share it with you
What about love
Don't you want someone to care about you
What about love
Don't let it slip away
What about love
I only want to share it with you
