- Hey, It's That Voice!: This is what every person in the audience was saying during her vocal parts in The Lord of the Rings movies.
- The soundtrack to the 1997 film Titanic had many thinking Enya had composed and recorded the music. Reportedly, James Cameron used Enya's music as a placeholder when editing the film, and when the time came to come up with a real soundtrack, he invited her to do it. Enya declined, so James Horner was commissioned to basically write a soundtrack in the Enya style. Sissel Kyrkjebo, a noted classic vocalist from Norway, was hired to provide Enya-like wordless vocals. Even elements of the (in)famous "My Heart Will Go On" love theme recorded by Céline Dion appear to reference Enya (at least, until Dion goes into full diva mode on the song).
- Keep Circulating the Tapes: The original 1986 Enya version of The Celts on the BBC label is very hard to find; it was replaced by a virtually identical release on Atlantic Records, and later her main label WEA reissued it in a remixed form, with one track replaced with an alternate take, and completely different artwork (replacing the off-piste images described in Early Installment Weirdness, above, with more on-brand imagery. The music video for "I Want Tomorrow" was never seen again, either ... at least not until BBC Video released The Celts on DVD in the mid-2000s.
- Production Posse: Enya is not quite a group, but lyricist Roma Ryan and producer Nicky Ryan are ever-present collaborators. It has been stated multiple times that "Enya" as an entity, consists of these three people. Indeed, as of 2014 Enya has yet to release a single recording that has not involved at least one of the Ryans, and that includes her time with Clannad, too.
- Promoted Fangirl/Official Fan-Submitted Content: Judging from the name of one track from her album Shepherd Moons, "Lothlórien", Enya (or Roma Ryan, or both) is a fan of The Lord of the Rings. Fast forward to 2001, when she was asked to produce music for the Peter Jackson films, with the result being two songs, "May It Be" (including lyrics in Quenya) and "Aniron" (with lyrics in Sindarin).
- Reclusive Artist: While she has made a few semi-live singing appearances, and gives the occasional interview, Enya prefers to stay out of the spotlight, and very rarely appears in public. Part of this can possibly be attributed to the fact that she's had stalkers in the past, some of whom have broken into her home.
- What Could Have Been: James Cameron wanted her to be the composer for Titanic (1997).
