Both platforms require titles to contain only the title — no promotional language, technical specifications, or duplicated metadata. The specific list of banned terms differs slightly by platform.
2.5.1 The shared principle
The standard release or track title must not include any additional information beyond the title itself, unless that information is genuinely needed to identify the content (see 2.6 for accepted version terms).
2.5.2 Terms banned from titles — Apple
Apple's explicit banned list includes: Exclusive, Limited Edition, Album Version, Original Mix, Tone/Alert Tone/Text Tone/Ringtone variants, E-Release, Digital Only, Digital Download, Digital Single, 2 CD Set, With Lyrics, Clips from, Official Music Video, Full Song Video, Full Version, and any audio-format reference (Atmos, Dolby Atmos, lossless, high-resolution audio, spatial audio, 24-bit, 192kHz, 128kHz, 96kHz). Apple also bans title text duplicating its own automatic badges: Clean Version, Explicit Version, Apple Digital Masters, Dolby Atmos, Lossless.
2.5.3 Terms banned from titles — Spotify
Spotify's metadata guide separately bans: references to competitors of Spotify, and the literal words CD, digital, digitally, album, EP, single (outside the dedicated product-type field) in the version field specifically. Spotify also separately bans SEO terms like "Sleep Music", "Chill", or "Music for Concentration" used as titles or version text — explicitly warning that titles appearing designed to mislead or confuse users may be removed from the platform, with repeat violations risking a strike or block.
2.5.4 Producer credits, track numbers, and search terms
None of these belong in the title field on either platform: producer credits like "(Prod. by X)", track numbers, search-term stuffing, or the artist's own name repeated in the track title (see 2.3.4 for Spotify's explicit rule on this).
2.5.5 English title casing (Apple's documented standard)
English titles use title case. The following are lowercase mid-title (not as the first or last word): a, an, and, as, but, for, from, nor, of, or, so, the, to, yet, and short prepositions of four letters or fewer (at, by, for, from, in, into, of, off, on, onto, out, over, to, up, with) unless used as another part of speech. The words Are, If, Is, It, Than, That, This are always capitalised regardless of position. The first and last word of a title — and the first and last word inside parentheses — are always capitalised.
