Capitalization Rules for Song Titles


1. The first and last words are always capitalized, and all except the
   words listed below are capitalized.


2. These are lower-case, unless they are the first word or last word.

   - articles: a, an, the
   - conjunctions: and, but, or, nor
   - prepositions that are less than five letters long: at, by, for,
     from, in, into, of, off, on, onto, out, over, to, up, with
   - as (only if it is followed by a noun)


3. Prepositions are sometimes capitalized.

   - Prepositions are capitalized when they are the first or last word.
   - Prepositions that are part of two-word "phrasal verbs" (Come On,
     Hold On, ...) are capitalized.
   - Prepositions that are over four letters long: across, after, among,
     beyond, ...


4. These short words are capitalized.

   Some people occasionally forget to capitalize these.
   - also, be, if, than, that, thus, when
   - as (if it is followed by a verb)
