Rainbow remixes

I wasn't sure where to put this, sorry if it's in the wrong place..

But I was wondering if there were any remixes of Ayumi's song, RAINBOW? I don't recall seeing any remixes she did or whatever, but does anyone know if there were any fanmade remixes?

I really liked the instrumental of the song on the actual album, but it was so short it was dumb. I really wanted a remix of it and the song Angel's song, but she never made any...
