How do i read 翼 in "one-winged"


I've encountered a song with romaji title `Katatsubasa no tenshi`, which I
would understand, but the other day someone handed me an album with romaji-ed
names, where the same song was written as `Katayoku no tenshi` so which is OK?




I have always heard this as `katayoku`.  
(e.g. _Umineko no Naku Koro ni_ makes plenty of references to a
[片翼]{katayoku}[の]{no}[鷲]{washi}.)

For what it's worth (maybe very little), Google IME also suggests this song
title as the first entry upon entering `katayoku` and does not recognize
`katatsubasa` as a 2-kanji compound.

There is some discussion
[here](http://detail.chiebukuro.yahoo.co.jp/qa/question_detail/q1136501161)
about this same song, where the answerers have the same opinion. The first
answer by ffbiyoriさん says that the word was coined fairly recently, and so the
reading varies, with `hen'yoku` and `katatsubasa` also being seen sometimes,
but less commonly than `katayoku`.

(Also note that if you search EDICT for [words ending in
翼](http://tangorin.com/general/%2a%E7%BF%BC), they all use the `yoku`
reading.)
