One friend downloaded this album a few days ago and today he said this to me.
I suppose the song is a remix.
And this is not the first time Ayu's song are in compilation album here (in Spain) because i have searched "AYU" in an online webstore and there are other 3 albums released in Spain with ayu's songs (remixes) in them:
Tunnel trance force, Vol.27
Track 18. Above & beyond - Ayu
(they forgot the "M" xD)
Dream Dance Vol. 27
Track 3. Connected - Ayu
Trance Tunning 2003
Track 6. M - Ayu
