Lyric added by: mugendaiHot, hot, hot, hot summer
Hot, hot, hot, hot (wind swound)
Hot, hot, hot, hot summer
Hot, hot, hot, hot (wind sound)
[Krystal] I might explode from holding back all the time
I want to change something right now
[Sulli] To produce you, who's about to wake up
Is it okay if you become too popular?
[Victoria] From over there, that dark room
[Amber] It's sunny today, so why don't you go outside?
[Luna] Burn like "jari" (onomatopoeia for being burnt) under the hot sunlight
A pair of sunglasses for your squinting eyes
[Krystal] The ice cubes are melting inside my mouth
The tall blue sky is pretty nice
Hot summer ah hot hot summer
hot summer ah hot hot This is it
hot summer ah hot hot summer
hot summer ah hot hot It's summer
Hot hot hot hot summer
hot hot hot hot (wind sound)
[Victoria] Even though it isn't a beach in Malibu
The waves sparkle like "kira" (onomatopoeia for sparkling)
[Luna] To eat ice cream with toppings
I don't need TV that's only full of gossip
[Amber] Even if I can't go home tonight
[Sulli] That's perfectly fine with me, let's go play
[Krystal] Poking at a love that has already ended
A pair of sunglasses for the eyes that looked at him
[Luna] The last of my feelings floating away
To the tall blue sky, which is pretty nice
Hot summer ah hot hot summer
hot summer ah hot hot This is it
hot summer ah hot hot summer
hot summer ah hot hot It's summer
[Sulli] I get even closer
With an affectionate heart
[Luna] Gently closing (lit: squeezing) in the distance
I'll break it
[Amber] Yeah! It must be burning
‘Cause I got you sweating in this weather
All them heads be turning
True that, you know I got it
[Krystal] Burn like "jari" under the hot sunlight (jari = onomatopeia for being burnt)
A pair of sunglasses for your squinting eyes
[Luna] The ice cubes are melting inside my mouth
The tall blue sky is pretty nice
Hot summer ah hot hot summer
Hot summer ah hot hot This is it
Hot summer ah hot hot summer
Hot summer ah hot hot It's summer
Hot summer ah hot hot summer
Hot summer ah hot hot It's summer
Hot hot hot hot summer
Hot hot hot hot summer

f(x) hwaiting! lovelovelove this version
I reaaally like this version
Omg I love Amber's rap XDDDD
Amber's so pretty XD
This song sounds really good in Japanese
For some reason I like this way better than the Korean version...
I think it's because the vocals are a bit slower, which matches up with the tempo of the song better
I love how they use paint in the last part of the video! Love this version more than the korean one.....f(x) fighting!
I love F(x)!!!!!
I love this version as much as the Korean version.
Amber's so cute 
I like their Korean version of this song..
the Jap is okay, though
what you mean is the Japanese aka JPN version
It's nice to see that these girls are getting the attention they deserve. Their Japanese is not very good but they are so energetic I hope that the Japanese will forgive them.
It sounds really good in Japanese. The PV was ok.
I have to say that SM videos are just so boring. Couple of dance videos with different sets and clothes, and close-up face videos mix together. I mean I don't even want to watch the rest of the video. It's just boring
better than the korean version

The MV is nothing original or special, but they look so awesome that it's ok like that
I would have liked a new song for the japanese debut.. but well.. we are used to this already.
WELL THE SONG IS......MMMMM....... AWESOME!!!!!!!! VICTORIAAAAAAAAA

Well now. Hm. I'm not too sure....
Wow, Luna & Sulli look amazing! All of them actually. It sounds pretty good in Japanese, I just have the Korean version etched into my head.
F(x)
33 Love them

LEMME LOL FOR A MOMENT. they took this song from the German band to sing it in Korean and now they're using it to promote in Japan as well. PLS make sth new and worthy.
also i heard the hallyu was declining in Japan so why are they even going to promote there?
i agree x_x japanese are getting annoyed with all the kpop apparently...they should have come up with something original.
