Hey Ryan.
Good post!
Personally, I like E-Type (but I suppose I like trashy, cheasy, Swedish pop). To me and E-Type track is a classic back track. But that's my personal taste. Yes, there is a lot out there and I'm sure it's a mine field negociating the licenses. Hence why we see so much of certain artists. Then again, that's not always back (i.e. Scooter :-) )
With regards to the breaks in the music, I'm afraid that's down to the Kiwi's music laws. We've been whinging about this in Combat for ages! It seems LM can't always remix songs. So in the past, they could remix the song to fit the choreography they wanted. Now they've got to make the choreography fit the music.
For instance, in the current Combat (39), in the upper body warm up, we do 8x Upper cuts and 8x Hooks in the first half, but then only four in the second. In the past, they'd have the song tweaked to even it out, but I suppose that is no more. Plus I think they have to have the big gaps in between the parts (i.e. the big pause in the lunges in BP 69).
Personally, what is irking me at the moment is reusing the songs, within the same release cycle across severl programs. Such as "So What" (Combat/Pump). "All I Ever Wanted" (Pump/Attack)
It's bad enough when a song from one program is in another program next time around, but this is just silly.
