f(x) announced the name, for the new title song on their new album and continue their vintage vibe with a new teaser image!
The title of their upcoming song, which has been named "Rum Pum Pum Pum" for English title ("First Wisdom Tooth" is the actual title of Korea), is a dance pop song that compares too late to find love first person to grow last wisdom tooth because it encourages addition to other teeth.

They are really going to kick their comeback stage before the release of the album, starting with their performance on 'M! Countdown' on the 25th.
