This year the Academy has set new standards for being nominated for Best Original Song. All eligible songs are graded by a scoring committee and only those songs which are given a grade of 8.25 (out of ten) or higher are to be nominated. If five songs score higher than 8.25 (the maximum allowed), then there will be five nominees. If NO songs get a score higher than 8.25, then there will be NO nominees and the category will be scrapped for that year.
But what if only one song grades higher than 8.25? Does that mean that it automatically wins? Not quite. That would mean that the next highest rated song would get a lucky bump and get nominated to compete against the other song. This is all done in the name of cutting down the bloat in the show and getting more people interested in watching again (and, I assume, most people weren’t interested in those long musical numbers).
