... so Disney itself won't even license the songs to use on their official ride? And instead choose to use different songs than the GOTG ones? No doubt they work - but still, that has got to tell people something when it comes to licensing songs. Why wouldn't Disney use the songs on their own rides?!

Not sure that's fair - you don't exactly go to Disneyworld or Disneyland and think "Wow, Disney is cheap with their stuff" or "This ride looks cheap". If anything, they almost spare no expense when it comes to their parks and experiences - it's full immersion. I think there's also a difference between "cheap" and "business conscience". They certainly put a lot of detail (money) into their parks that are minuscule and not noticeable to a lot of people. I'd personally think the GOTG music would not be something they would cheap out on as it is a big part of the experience. There must be more to it than that.
