Before you go, we thought you'd like these...  2015 was a massive year for music: Between Justin Bieber's apology tour, Selena Gomez's maturation, and Fetty Wap's introduction to the world, there were too many big stories to keep track of.  Here we've put together our list of the 10 best songs of the year, and it was hard to pick just 10. Some songs were chosen based on significance of an artist's new direction or comeback, while other's were picked because they represented a new artist's potential for greatness. What they all have in common, though, are there quality: All of them are incredible songs.  Without further ado, here are the best 10 songs of the year:  1. "Where Are Ü Now" by Jack Ü feat. Justin Bieber  2015 was the year that Justin Bieber (or, at least, his music) came back into the public's good graces. "Where Are Ü Now" was inescapable at the height of its popularity -- it's high-pitched, dolphin-like refrain will never get old -- but this song was even better for its reintroduction of the Biebs. Consider its presence at the top of our list a stand-in for his other amazing hits, "What Do You Mean?," "Sorry" and "Love Yourself."  2. "Can't Feel My Face" by The Weeknd  "I can't feel my face when I'm with you / But I love it" is perhaps the most memorable refrain of the year, even if we're not totally sure what it means. The Weeknd had spent years as the Internet's favorite cult artist, but 2015 was the year that the whole world got to hear his genius. "Can't Feel My Face" is the product of his collaboration with pop mastermind Max Martin, and it was perfect.  3. "Run Away With Me" by Carly Rae Jepsen  After surging to the top of the charts and into our inner eardrums with the inescapable "Call Me Maybe" in 2012, Jepsen disappeared for a while to reinvent herself -- because, really, how do you follow such a massive hit? With her critically-acclaimed album, Emotion. "Run Away With Me" is the best song on the album with its exuberantly soaring chorus and pulsing, reflective verses -- this is pop at its best.  4. "When We Were Young" by Adele  Adele came roaring back into our lives with three one instantly-iconic phrase: "Hello, it's me." "Hello" is an incredible song in its own right, but "When We Were Young" is our favorite off of her much-talked-about, record-breaking album, 25. It's Adele at her best -- nostalgic, vulnerable and angry. Welcome back, Adele.  (Photo by Sascha Steinbach/Getty Images)  5. "Good For You" by Selena Gomez  If 2015 was the year that the world "forgave" Justin Bieber, it was also the year that his ex (are they or aren't they?) proved she had officially grown up. "Good For You" is a steamy, sensual mid-tempo jam that feels equally as appropriate for the dance floor and the bedroom. Gomez had a message to deliver with this one, and we totally received it: She's an adult now, y'all!  6. "Here" by Alessia Cara  Our favorite new artist of the year, Alessia Cara, broke out with a song about hanging out in the corner at a party she doesn't want to be at. If that doesn't make you love her, what will? "Here" is a cool, addictive song that seems to indicate a bright future for the young star.  (Photo by Jamie McCarthy/Getty Images for iHeartMedia)  7. "Hotline Bling" by Drake  "She used to call me on my cellphone..." Drake had a huge 2015, but no song of his was as big for him as "Hotline Bling," the best song about booty calls in years, and a true cultural moment. Much was made about the (also wonderful) music video, but the song itself it a true party starter.

Though none of their follow-up singles have yet to live up to the precedent that they set for themselves with "Roses," we're excited about what other jams the pair cooks up.

"Trap Queen" by Fetty Wap  If you had told us twelve months ago that one of the year's best new artists would be a rapper with one eye, we never would've believed you. "Trap Queen" was one of the biggest hits of the year, and Fetty Wap followed it up with a handful of other hit songs. Hey, what's up, hello, Fetty Wap. We can't wait to hear what you release next.

She sang on Clean Bandit's worldwide smash, "Rather Be." With "Hold My Hand," which was a number one hit in the UK, Glynne gets it right on her own -- it's a euphoric, feel-good jam sure to get you in an amazing mood.
