So this is my opinion, 2017 has been a good year with lots of bops! Not in order, here are some really good songs I've heard this year. Others I might miss out since I don't really listen to a lot of groups, while others I just listen to one song or a few songs. Also to not show any biasness I only use one song per group :D

BTS- Spring Day (Song of the universe, MV of the universe, Choreo of the universe, one of the greatest songs by Bangtan, way better than DNA tbh) 
EXO- The Eve (Why is this song less than 3 minutes-)
Monsta X- Dramarama (Monsta X broke through this year, I'm watching them fondly from a distance, waiting for the right moment to start stanning-)
Seventeen- Don't Wanna Cry (I chose this over Clap but both are as good)
Day6- Hi Hello (My favourite EveryDay6 title song. Scroll down for my favourite B Side) 
Stray Kids- Hellevator (Out of all the survival show songs I've heard, this sounds the most desperate and beautiful)
BTOB- Missing You (My favourite ballad of the year)
Block B- Yesterday (Why is this song less than 3 minutes- pt. 2)
Wanna One- Beautiful (I linked the performance version bcs the actual MV is 8 minutes long)
Vixx- Shangri-La (I love the Chinese traditional instruments sounds here)
Produce 101- Never (There is also a Wanna One version of this song but Nation's Son is the best okay)
Super Junior- Black Suit (A legendary song by a legendary group)
Winner- Really Really (Everyone points to this song at least once this year. Award shows wyd this the song of the year)
Nu'est W- Where You At (I knew them through P101 and whoa I might start stanning idk)
SF9- O Sole Mio (I only listen to this song of theirs tbh)
GOT7- You Are (I don't understand why people said they flopped this comeback , song is lit everything is nice)
NCT 127- Limitless (This is the perforamance version because I don't stan NCT and why are there 2 versions)
The Rose- Sorry (The opening line absolutely b r o k e me)
BAP- Honeymoon (Both this and Wake Me Up are so good)
JBJ- Fantasy (A steady start for JBJ, I hope their contracts get extended)
Highlight- Plz Don't Be Sad (A song to party to)

Twice- Knock Knock (Knock Knock is obviously better than Signal in my opinion)
GFriend- Love Whisper (This song and Summer Rain is almost the same song lmao just the tempo and some chords are alternated)
Blackpink- As If It's Your Last (My personal summer bop)
Dreamcatcher- Fly High (Every song from them sounds an anime opening)
Fromis_9- Glass Shoes (I'm not really fond of them but this song is good)
2NE1- Goodbye (Sadly, we say goodbye to some legends this year... I hope the rumours about 2NE1 not really over is true)
Girl's Day- I'll Be Yours (Queens of iness tbh)
Weki Meki- I Don't Like Your Girlfriend (I personally prefer WM over Pristin maybe bcs my IOI bias is here?)
Red Velvet- Peekaboo (How is it even possible? Red Velvet keep outdoing themselves. The next legendary girl group in making)
Mamamoo- Yes I Am (Vocal queens)

Taeyang- Wake Me Up (I was seriously torn between Darling and this but Wake Me Up's MV won me over)
Zico- Artist (The hook brainwashed me)
GD- Untitled, 2014 (King. Legend. Whatever.)
Samuel ft. Changmo- Sixteen (Aww so fresh I'm still a lil bit sad he's not in W1 but look how well he is doing)
Taemin- Move (There are 3 versions of this MV, I only linked the first version)

IU- Through The Night (Such a gorgeous song, 100% deserve album of the year. Actually the whole album is so nice!)
Taeyeon- Make Me Love You (A song that cheers me up a lot)
Heize ft Shin Yong Jae- You Clouds Rain (Recently started listening to Heize, thought she only rapped because of Unpretty Rapstar but she has a nice voice)
Suran- Wine (No MV for this song so I linked a lyrics video. Prod by Min PD so it's definitely nice)
Sunmi- Gashina (Another bop, I love the point choreo)
Chungha- Why Don't You Know (The choreo is a lil bit... yeah. My reaction is same as Daehwi's here lol I turned away)

KARD- Don't Recall (Still one of their best songs after Oh Nana)
Seventeen Vocal Team- Pinwheel (So emotional and beautiful)

Bonus:
BTS- Best of Me
BTS- Sea
BTS- Crystal Snow (this is the only clear audio on Youtube ugh so here are the lyrics)
You should read the lyrics to those songs!

Day6- My Day
Day6- Lean On Me
Day6- I Need Somebody
Day6- Man In A Movie
Day6- I'll Remember
Day6- I Would
Those are B sides to EveryDay6 projects this year, and seriously you should just check out every single Day6 song ever there isn't any single bad song!

Well that's about all lol. I hope I don't link any songs wrong!
