Each and every week we put together our favorite tracks that had premiered a few days prior into one magnificent mixtape to share with you and your friends. This time around we've decided to share new 2015 songs from Justin Bieber, Selena Gomez, Usher, Nas, Diplo and more right here!

You can check out more buzzing news coverage from Music Times right here!

This past week saw a lot of great collaborations between artists, resulting in some of the best songs of the year. Easily the biggest example of this trend was "Strong," a new duet between former boyfriend and girlfriend Justin Bieber and Selena Gomez. Go ahead and talk about some dating rumors or whatever you want, we're just excited to share this great new pop hit with you today. Check it out right here!

Another great (probably much more important in the bigger picture of music) collaboration teamed iconic hip-hop artist Nas and R&B heartthrob Usher on "Chains." Taking on the tough issues of police brutality and racism, this song is a reminder of how big performers can still get a message across. You can watch the music video for "Chains" exclusively on TIDAL.

We all love when Diplo and MØ make music together, so we were definitely into their release this week: "Kamikaze." This song is a great reminder of why they keep working together. Check it out right here!

Our final collaboration that we're sharing with you is the new Courtney Barnett song, "Boxing Day Blues," which is part of Third Man Records' Blue Series. Barnett and Jack White worked on this song and her recent "Shivers" cover, making us hope more teamwork is in the future for these two songwriters. Check out this new track right here:

While collabs are pretty cool, nothing beats remixes or covers in our minds!

Check out Pharrell's remix of A Tribe Called Quest's "Bonita Applebum" right here!

Check out Chance the Rapper's studio version of his cover Kanye West's "Family Business" here!

"A Dream Is a Wish Your Heart Makes," the classic Cinderella tune, was covered by Jessie Ware! Check it out!

Did you ever think "Raining Blood" by Slayer could sound smooth and jazzy? Check out Natalie Press' cover right here and be amazed!

Getting back to originals, The National premiered a brand new song this past week during a live performance in Los Angeles at a benefit concert. Entitled "Roman Candle," this is our first taste of what's to come from the indie band. Check it out right here:

Electro-pop duo Chairlift shared their new song "Ch-Ching" this week, which is going to get caught in your head by the end of the day. Check it out right here!
