For those of you who like "Adrenaline" but wanted it to be even more electronic, "Dangerous" is the song for you.
In 2010, f(x)'s "Nu ABO" was one of my favorite songs of the year. It was the song that cemented them as one of my favorite groups. "Dangerous" reminds me of "Nu ABO" with a lot more autotune, but it works very well how the instrumental sounds.
At first, I didn't like this song that much because in 2010 the heavily autotuned vocals were too prevalent in songs, but after the fad ended, the song became much more enjoyable for me. I had always loved the instrumental of the song, as I am a sucker for electronic music.
