WATCH: Ellie Goulding Copes With Breakup in 'Figure 8' Video

While the video for "Figure 8" was in the works for some time, given Ellie Goulding's recent breakup with EDM star Skrillex, it's interesting to see the young British singer struggling with the loss of a recent lover in the new visuals. In the clip, she copes with the split by holding on to her former beau's belongings, laying in bed all day and recalling memories of the relationship.

WATCH: Florence & the Machine Debuts 'Lover to Lover' Video

In the latest video from Florence and the Machine, one of the strongest tracks off the year-old Ceremonials album is on display with "Lover to Lover." Ms. Welch is featured in the piece alongside Australian actor Ben Mendelsohn as a troubled duo that can't seem to work things out. In a dramatic finish that includes massive flames and a dive into the sea, it's certainly one of the best sets of visuals from this act.

Fresh off a tour with NEEDTOBREATHE and Good Old War, indie rocker Matthew Mayfield debuted on Monday morning a new video showcasing the track "Take What I Can Get" off his newest album A Banquet for Ghosts, which released earlier this year.

WATCH: Beach House Debuts 'Wild' Video

Beach House’s new video definitely lives up to its name. The visuals for “Wild,” off their latest set Bloom, tell the story of an unhappy relationship, romantic violence and obsession. While the story is not the easiest to follow, with isolated moments of fury chopped up into small bits, one gets a vague id ea of a painful unraveling. It's certainly an intense piece of work, which can be seen below.

WATCH: Nada Surf Debuts 'Jules and Jim' Video, Adds Tour Dates

Nada Surf is finishing an excellent 2012 by releasing the music video for the song "Jules and Jim," from their critically acclaimed album The Stars Are Indifferent To Astronomy (Barsuk). The film was directed, animated and edited by Rachel Chaiya Blumberg. Filmed over the span of several months on location in Arch Cape, Ore., and in Providence, R.I., it gently alludes to the classic French new wave film of the same name. Following their latest leg of European tour dates, this December Nada Surf will close out the year with a string of gigs across the mid-west and east coast, including a pair of home town shows in New York City at Bowery Ballroom. Upcoming dates listed below video.

WATCH: Björk Debuts Unusual 'Mutual Core' Music Video

In typical Björk fashion, her newest music video for "Mutual Core" is an unusual and rather strange set of visuals. Ahead of her Bastards remix album, which releases Nov. 19, the latest clip is certainly difficult to interpret, but at least it's consistent. Regardless, it's good to have Björk active again. That's something we all can appreciate.
