iTunes insist on full and comprehensive details regarding the title of the song, catalogue number, spelling and syntax. iTunes are also very sensitive about titles having the correct casing. Some example of the correct casing and syntax can be found below. These examples have been taken from iTunes’s style guide: French Suite No. 5 in G Major, BWV 816: Allemande Symphony No. 2 in D Major, Op. 73: Feierlich. Misterioso Note that there are spaces inserted before numbers; “Major” has been included in the key information with the M capitalised. A comma is present before the catalogue number; the major work title is followed by a colon, and then the movement title.
