After another trawl through the iTunes store and my music library here are some suggestions of music for Advent. Christmas music to come later.
- O Come, O Come Emmanuel - of course! I downloaded the version by the choir of King's College, Cambridge.
- Gabriel's Message, also performed by King's College Choir
- Advent Mass and Vespers from Chant - Music for Paradise by Cistercian Monks of Stift Heiligenkreuz
- The Kingdom Triumphant by Eric Ball (Norman Law and Sellers Engineering Band) - rousing brass band setting of three Advent carols. Not sure what the first is, but it segues into O Come, O Come Emmanuel and ends with Lo, He Comes With Clouds Descending.
- Christmas is Now Drawing Near at Hand (traditional), from Frost and Fire, The Watersons
- Canticle to St. Nicholas, performed by St. Eliyah Children's Choir - beautiful Orthodox hymn
- St. Nicolas Cantata by Benjamin Britten
- The Advent Polka / St. Nick's Brawl, The Albion Christmas Band - fiddle music
- Santa Claus is Coming to Town
- When Santa Got Stuck Up the Chimney
- Rudolf the Red Nosed Reindeer
- Immaculate Mary (hymn)
- Gregorian Chant: Graduale Romanum - Missa in Conceptione Immaculata
- Gaudete (medieval hymn) - I like the folk version by Steeleye Span
- Seven Magnificat Antiphons by Arvo Part
- Advent Carols from St. John's: Antiphons, performed by choir of St. John's College - plainchant
