These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
It's par for the course for these shows to incorporate Disney productions, old and/or new, that are currently getting a heavy push from the company. For example, Let's Celebrate! (2009) features a segment based around The Princess and the Frog. They haven't always made the best choices, though...look for the cast of TRON in this commercial for one of the early '80s shows.
The Hercules adaptation might have also suffered from this, as the story was incorporated into a program centered on true love. Musical sequences such as "A Whole New World" and "So This is Love" preceded the irreverent, action-packed, occasionally romantic story of Hercules and Megara.
