2nd generation · SM Entertainment
エフエックス / 에프엑스
f(x) made the strangest records SM Entertainment released, and the albums have aged better than almost anything else from their years.
Last updated:
Victoria, Amber, Luna and Krystal worked with Sulli until 2015, and the run from LA chA TA through Pink Tape to 4 Walls keeps getting more assured.
Start here if you judge groups by albums rather than singles; this is the strongest case in second-generation pop.

Follow a few songs from the starting point to the group's current sound.
Electric Shock MVElectric Shock is the most addictive of the singles and the usual first listen.
Rum Pum Pum Pum MVRum Pum Pum Pum comes from Pink Tape and shows how odd the writing was willing to get.
4 Walls MV4 Walls is the most refined thing in the catalogue and the best argument for the whole project.Verified English information is not yet available for this section.

f(x) turns on experimental electro pop and on being judged album by album. The SM Entertainment girl group debuted in 2009 with LA chA TA, and separating the line of Victoria, Amber, Luna and Krystal from the stretch when Sulli took part, from the beginning through 2015, makes both the release history and the present route easier to sort.
Entry points are LA chA TA, Nu ABO, Electric Shock, Rum Pum Pum Pum, Red Light and 4 Walls. Pink Tape and 4 Walls both hold up as albums, and watching the performance footage rather than only the music videos is what carries the forward-looking side of f(x) across.
The releases run from the 2009 debut to All Mine in 2016, with the era of Sulli's participation and the 4-member era kept apart in chronological order. In the order Nu ABO, Electric Shock, 4 Walls, you pass through the experimentation, the signature song and the album-level regard.
Editors' take Nu ABO / Electric Shock / 4 Walls — an SM 4-piece whose experimental electro pop and album-level regard come through in 3 songs.
No. 182 of 210 groups with recorded activity in Japan (top 87%)
The denominator is the 210 groups, out of 525 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
