Should "Best Original Song" Singers Get Oscars?

[obriensg1]

I was thinking about this earlier. I played back the full version of 'I See the Light' from "Tangled" when I saw it got nominated for an Oscar. It's easily my choice for the win. Definitely not Randy Newman's song from "Toy Story 3". (shudder).

Should the performers of a song win Oscars as well? Only the lyricists and composer do, but where would the song be without those people in the film who bring it to life? Now yes sometimes they win the oscar, if they shared one of the above listed jobs, but even if they didn't, I think they should get one.

Now maybe it could get confusing I guess on who qualifies then. For example, in "Aladdin" you had two excellent versions of "A Whole New World" (A much deserving winner itself) where in the movie itself Brad Kane and Lea Salonga sang it, and in the ending credits Peabo Bryson & Regina Belle sang the version that made me wear out that part of the VHS when I was a kid.

So you tell me. Take "I See The Light" for example. I think Mandy Moore and Zachary Levi deserve Oscars here if the song wins. http://www.youtube.com/watch?v=p3QqD3GVdPw
