Both newcomers and established artists delivered some of the best R&B music in 2015. The competition for Best R&B Song of the Year in The Boombox Fan Choice Awards is serious.

To kick it off, we have the Weeknd, who released the stellar album, Beauty Behind the Madness. Two big hits from the collection are the BDSM anthem “Earned It” and the drug-induced ballad, “The Hills.”

After a four-year hiatus, Adele released the emotional song “Hello,” which made us get into our own feelings with her somber lyrics. Another female artist who burned up the charts is Rihanna. The R&B star cashed in on her infectious song, “Bitch Better Have My Money.”

There are also several newcomers who made waves in R&B. Kehlani's song "Bright" was a fan-favorite on her mixtape, You Should Be Here. Fellow crooner Bryson Tiller gave us trap soul with his ballad, "Don't." Finally, Natalie La Rose had the clubs rocking with her dance track, "Somebody" featuring Jeremih.

Meanwhile, Andra Day and Leon Bridges delivered beautifully written soul gems, “Rise Up” and "Coming Home," respectively. Alessia Cara impressed us with her breakthrough hit, "Here" while southern singer Raury showcased his blend of soulful funk with "Devil's Whisper."

Established artists like Miguel woke us up with "Coffee" featuring Wale, Chris Brown got us drunk with "Liquor" and Jazmine Sullivan returned to the scene with her kick-him-to-the-curb anthem "Dumb" featuring Meek Mill.

Other R&B songs mentioned on this list include August Alsina's "Why I Do It" featuring Lil Wayne, Ciara's “I Bet, Tory Lanez's “Say It," FKA twigs' "In Time," Kelela's “A Message" and Frank Ocean's Aaliyah tribute, “At Your Best You Are Love.”
