Kin Fables by Five Knights Productions is an excellent series of short independent films with fairy themes
Dr. Jenny Butler gives a great interview on youtube about Irish Fairy Lore
There's also this short video of a modern fairy encounter that I recommend people watch.
Michael Fortune has a wonderful series of videos on Irish folklore, some of which focus on fairy beliefs. These are must watch in my opinion.
You can find several videos of Eddie Lenihan on youtube, of varying quality, and I suggest watching them all. Lenihan is a well known story teller in Ireland and he has fought in the past to keep a fairy tree from being destroyed for the sake of a road.
Lora O'Brien offers a fabulous class on the Irish Sidhe on her website.
Fiction and Poetry
Charmingly Antiquated on Tumblr has a great comic about a university taken over by the Fey.
Five Knights Productions also has a graphic novel series titled Kin available online
Rosamund Hodge has an excellent short story online called 'A Guide for Young Ladies Entering the Service of the Fairies'
Lora O'Brien's 'The Fairy Lover' is a fascinating look at the Leanan Sidhe, and 'The Banshee in Italy' is worth a read for certain.
Author Jennifer Lawrence has several excellent pieces online including 'Tam Lin's Garden' and 'Rebuttal: The Faerie Queen's Reply' that represent good, modern takes on the story of Tam Lin
Professor Ashliman of the University of Pittsburgh has a very useful site called 'Folktexts' that I recommend people checking out as a solid online non-fiction resource
Another great non-fiction source is the folklore site Duchas. There is a great deal of fairylore to be found there, although in fairness not all has been transcribed into English.
Audio Resources and Music
Bluirni Bealoidis has a great podcast focused on fairies titled 'Fairy Forts in Folk Tradition'
The BBC program 'In Our Time' has an episode titled 'Fairies' that presents a variety of views on the subject
There's a large array of songs that could be recommended, of course, but below I'll offer a selection of some that keep with the more traditional views.
Heather Dale, "The Changeling Child' and 'The Maiden and the Selkie'
Mor Gwyddelig's version of Buain a Rainich is very good and bilingual.
There's also several good versions of Tha Mi Sgith or A Fairy's Love Song.
Coyote Run has a very good take on fairy lore with their song 'Finnean's Dance'
Some of the old ballads can be listened to as well such as 'Lady Isabel and the Elf Knight' and 'Tam Lin'.
I'll end with one of my favorites songs with a fairy theme:
