I usually have a hard time doing a list for a year, cause I don't really pay attention much to when something is released.
But from the top of my head, it goes like this (order is random).
TOP 10 songs
Spoiler:
01. DAOKO x Kenshi Yonezu - Uchiage Hanabi
I'm probably biased, cause I experienced the success of this song myself this summer in Japan. It really creates such a warm nostalgic feeling when listening to it, even for the first time. It does remind me of a summer breeze while watching fireworks. And it does show that Daoko can actually sing if she wants to.
02. FAKY - Surrender
One of the songs I listened to the most this year. Creates this strong, but longing for more feeling.
03. Ai feat. Kanna - KIRA KIRA
I'm actually not a fan of Ai, but this song really surprised me. I love it!
04. Che'nelle - Outta Love feat. MINMI
"Just" an album song, but it took me completely over. I got hooked on it, meaning the replay value is really high for me. Doesn't happen that often anymore. Also like Destiny as a song really much.
05. BoA - Jazzclub
Ok, this will only be officially released next year, but the MV was made public this year. I wasn't a fan of her last Japanese singles, but this song is gold. Totally my thing!
06. Taichi Mukai - Sora feat. SALU
Ok, this was quite hard, cause I love quite a bunch of his songs he released this year. And I also never expected this, cause I didn't like it with first listen. But it grew on me so much and just clicked with the PV, I guess, and got me hooked. Plus the concept and the lyrics are amazing!
07. Ai Otsuka - FrogFlag
I do have more than one favourite song from her album (Tokyo Sanpo or make up e.g.), but her voice just sounds awesome in this one, so full.
08. Namie Amuro - Mint
Namie is very hit or miss with me with her fast songs (ballads I mostly don't care about). And with Mint she managed to get me hooked again! I know, the single is from last year, but as it is part of Finally, it counts for me.
09. Chanmina - My Name
Another surprise for me from this year. The whole album is great. But love this song to death especially.
10. Uru - The last rain
The full album was, like I expected, a disappointment. Pretty much only ballads, but not so many good ones. Her first single ever, The last rain, is still damn amazing though.
So, with the list of my favourite songs you already get a hint of my favourite albums.
There's just one addition actually, Koda Kumi. There's not a single song from her that stood out this year from the rest, meaning one that would be so much better than any other for me. There are quite a bunch I like equally and I do think altogether the albums were strong.
But that's the reason, she's not in my top song list.
Top albums of 2017:
FAKY - Unwrapped
Ai Otsuka - LOVE HONEY
Koda Kumi - W FACE ~inside~/ ~outside~
Chanmina - CHOCOLATE
Taichi Mukai - BLUE
As I'm also a K-Pop and C-Pop listener, I mention my favourites there, too.
K-POP/C-Pop albums 2017
Lee Hyori - Black
Another surprise for me. Always ever liked certain songs from her, but this time the whole album is amazing (and pretty unusual in style overall). It has a bunch of songs I love.
Red Velvet - Red Summer
A mini-album for summer with a nice selection of catchy electronic based songs.
MAMAMOO - Purple
Don't like all songs on this mini-album, but the strong ones outshine the weak (love 3 , dislike 2). Just love them for their quirky mix.
aMEI - Story Thief
It is similar to Lee Hyori's Black in style, but not as consistent. Lots of cheesy ballads like happening often for Taiwan and China. But also more than one strong song and one of the ballads got me hooked as well (#7 Left Behind).
+ BoA's CAMO
Wasn't too fond of her last Korean releases as well, but CAMO is awesome.
BoA is definitely going in the right direction again for me both in Japan and Korea.
@Kacku
You're reminding me, that I still have to listen to Nana Kitade's new album!
