In 2020, because their "ex-mentor & agent" Lin Weizhe registered the "Sodagreen" trademark first, the band had to use the new name "魚丁糸" (a part of each of the three traditional Chinese characters for "Sodagreen 蘇打綠", literally meaning "fish nail spool") and the English name is Oaeen (also derived from the words "soda" and "green").

In May 2001, Sodagreen competed in the Golden Melody Cup held by the National Chengchi University and won the Best Popularity award with the composition "Peeping".

In October 2006, they released their second album, Little Universe, followed by a single in December- My Future Is Not a Dream, a collaboration with A-pay, a band under the same label.

Wu Tsing-Fong also received the highly coveted Best Melody award for Little Love Song, which was also nominated for best lyrics.

In 2009, Sodagreen began its Vivaldi Project, planning to record and release four concept albums based on the four seasons within two years.

The song Enjoy Loneliness received online prominence after Wu performed it on the talk show Kangxi Lai Le.

The music video for the titular song What is Troubling You also trended worldwide on video-sharing website YouTube for a few days after its release.

Shortly before A-fu's discharge in January 2012, the band announced that its third Taipei Arena concert, Walk Together, would be held in March that year.

[4] Shortly after ending the Walk Together World Tour in Shanghai on 3 August 2013, Sodagreen announced that Autumn: Stories, the third installment in the band's Vivaldi Project, would be released on 18 September 2013.

The release of the album in September was accompanied by six live house performances in Beijing, with tickets to these mini-concerts selling out within ten minutes of the opening of online booking services.

[6] His appearance was a success despite finishing as the series' runner-up and losing to the winner Liu Huan in the finals held on April 12, 2019.

Also this year, their hit "No Sleep (無眠)" was adapted to merengue in Spanish by Dominican singer Luys Bien.

This record included all tracks from Sodagreen, as well as four new cover songs: "ㄐㄧㄢ視" by Sandee Chen, "忧愁" by 小安, "Pretty Thing" by Charlotte Martin, and "That I Would Be Good" by Alanis Morissette.
