BEST NIGHT
MADONNA
I always respected Madonna, but I was never a fan of her work. "Rebel Heart" was the first Madonna album I could get into, thanks to some masterpieces, including "Best Night." I love the softness of the song.
2011: Nicole Scherzinger - Don't Hold Your Breath 2012: Train - Mermaid 2013: Little Boots - Satellite 2014: Foxes - Let Go for Tonight
I COULD BE
SHANE FILAN & NADINE COYLE
It's for you, sumthintoxic82! "I Could Be" is probably the cutest song I heard this year. I like folk music, so it was love at first listen. The chemistry between Shane and Nadine is incredible, their voices complement each other perfectly. I can say it was the best duet in 2015. All I want for 2016 is a new Nadine album, please.
2011: Britney Spears – Up N' Down 2012: Leona Lewis - Favourite Scar 2013: OneRepublic - Counting Stars 2014: Pixie Lott - Heart Cry
UNDISCOVERED
LAURA WELSH
Laura Welsh was undiscovered before the release of "Fifty Shades of Grey" OST. I liked the film (shame on me, I know), but I wasn't happy that this song wasn't heard in it, it was just featured on the soundtrack. Laura's voice is so unique.
2011: Jessie J - Who's Laughing Now 2012: Nelly Furtado - Play 2013: Beyoncé - Pretty Hurts 2014: The Veronicas - If You Love Someone
TOM'S DINER
GIORGIO MORODER FEAT. BRITNEY SPEARS
Queen of covers is back with a classic. Unfortunately, "Pretty Girls" overshadowed this amazing re-make, so this year wasn't perfect in Britney world. I'm just glad that this song happened and I hope people will remember this more than the other one.
2011: The Saturdays - The Way You Watch Me (feat. Travie McCoy) 2012: Aura Dione - Masterpiece 2013: Jason Derulo - Vertigo (feat. Jordin Sparks) 2014: Beyoncé - Pretty Hurts
NEVER GET TO HOLD YOU
CARLY RAE JEPSEN
The best song from "E•MO•TION" is a Japanese bonus track. What a marketing plan! In this song, Carly shows another side of herself, proving me that she can be a versatile artist.
2011: Britney Spears - He About to Lose Me 2012: will.i.am - Scream & Shout (feat. Britney Spears) 2013: Justin Timberlake - Only When I Walk Away 2014: Natalia Kills - Trouble
I used to love her so much but then she went generic and lost track of her. 
OMG YOU HAD RUNNIN'on this char tby Nadine in 2011
50SOG soundtrack is sooo good.
This song slays!!
