You are probably OK if you buy the CD containing the suggested song, and play it in the privacy of your home or laser studio. Once you begin to play the song in public, or for commercial purposes, then you should be obtaining music rights. Pangolin is not performing the music, nor are we presenting synchronized images and music. Therefore, you are fully responsible should any music rights issues arise. We have obtained laser-related rights which transfer to most clients.
Details are in the text files located in each song's directory.
You can purchase royalty-free music from many sources. It is relatively simple in Showtime to readjust the show timing to work with a similar piece of music. Thus, if you have any questions or concerns, use royalty-free music instead of the artist's suggested songs. LD2000 comes with over 35 free laser shows. Here is a list of the show names, plus the suggested songs for use with these shows.
