In a song from a music library (sonoton.com) I recognized a melody very similar to a well-known trance tune (probably a few years old).

Here you can listen to the song from the music library:
Lady Dance (by D.J. Crissy, D.J. Hotnail, Xyco)
Amazon snippet: http://www.amazon.com/lady-dance/dp/B0011X77PG
Full song (MP3): http://www.dyrup.com/html/colourmus...ntemporary).mp3

The melody I'm talking about starts at about 0:30 in the full song.
It seems to be a rip-off but I can't remember the original.

Do you know a trance tune with a similar melody?

Thanks in advance!
