Lights move according to music. For the first song strobing can be too much, sorry for that, musicians liked it like that ;). If this is uncomfortable, you can press F key to freeze lights changes (I implemented this feature exactly for that). Second and third songs are much gentler, so you may try checking those out (keys 1,2,3 change the song, keys 4,5,6 change the head for the current song).
