Songmixes on Free Beam shows

In the Download section of showeditor, there are some great beam shows, synchronized with music songs, however I don't succeed Always to get the songs syncrhonized with the lasershow. Also, you have some beam shows with songmix, so several songs are mixed in a lasershow.

What can I do to find out details about these songmixes. I would be very interested to try them out, but there aren't any further details about the song mix. Can someone help me out with this?

Beste Regards,
Mario
