Ahhh, the perennial music question. Over the years, many people have expressed dislike for the post-Intensity and Body Blast series music. Other people are less picky and seem to like pretty much anything Cathe puts out.
I really dislike the music in the 4DS and think the music is getting more generic as more DVD series come out. Boo hoo. As an earlier poster said, it sounds like a guy went into a sound booth and created some artificial music that met the beats-per-minute required of the workout. There is no soul in some of the songs. (What I really dislike from the new workouts are the outer-space-sounding song in the Kickboxing strength training segment and the "remixed" Asian-New Agey song in either HIS or LIS cardio. Total turnoff.)
I agree with some posters that it's less important that the strength training songs be as driving and motivational as the cardio songs. For example, I really dislike the Halloween-inspired organ-sounding songs of the Body Max 2 cardio. (The warmup song sounds like the singer is going to jump off a bridge at any time.) The strength training songs on that video don't bother me. (They don't have that Halloween-sounding beat, however.)
Given that it is expensive to purchase the rights to use songs on DVDs, perhaps the STS workout can re-use the hundreds of already-used songs, and tweak some so they sound different. How about a remix of the remixed Pina Colada song? Another option is to create a competition for local bands to submit songs to be remixed for video use? That way, it would be real songs that are remixed, instead of generic, elevator-sounding songs that have no foundation in a real song. The local musicians would do the work of creating a catchy song, and they would get the benefit of hearing their song being used, even if it's not on the radio.
I am sorry to say, that despite the otherwise EXCELLENT choreography, production, and spirit of Cathe videos, I have been extremely selective in my purchases in the last few years. That's a bummer.
