I think it's possible that Disney splits the categories that it's up for at the Oscars this year. Best Animated could go to Zootopia, while Best Original Song goes to "How Far I'll Go" from Moana... Which would complete Lin Manuel Miranda's incredibly short quest to get his EGOT.
That's one of the things that disappointed me about the movie, actually. Despite the great songwriters, there wasn't a huge stand out hit, like Let It Go, Colors of the Wind, Part of Your World, or anything from The Lion King & Beauty and the Beast. The songs were great, but while "How Far I'll Go", "You're Welcome" and "Shiny" were fun, they don't hold a candle to some of the other soundtracks.
