WildStar's OST can make even the most dull tasks in FFXIV feel epic.. ;3

If not that, then it could be anything from movie or musical soundtracks (some favorites include my Disney playlist, Interstellar, Aida, The Road to El Dorado, LotR) to various rock genres (Heart, FoB, 3EB, Simon & Garfunkle, Decemberists, Queen, to name a few) to misc genres (Vienna Teng, The Lumineers, Loreena McKennit, Emily Smith, Jenny Dalton, to name a few) to a wide range of chamber and orchestral stuff (Tchaikovsky - prefer his symphonies, Dvorak, Vivaldi's oboe concerti, spanish vocal concerti, and more modern chamber groups like the Piano Guys). xD It honestly just depends on what I feel like on any given day.
