Sodagreen is a Taiwanese indie band formed in 2001. Its members have been unchanged since 2003. Sodagreen emerged in the Taiwanese indie music scene after receiving the Grand Jury Award in the Hohaiyan Gongliau Rock Festival in 2004, after which it signed a contract with Willlin Music. The band is the first indie band to hold a concert in the Taipei Arena.
In 2020, because their "ex-mentor & agent" Lin Weizhe registered the "Sodagreen" trademark first, they had to use the new name "魚丁糸", and the English name is Oaeen.
On May 30 2022, the 18th anniversary of Sodagreen's debut, Lin Weizhe stated to give up the "Sodagreen" trademark rights, and Wu Qingfeng and other 5 team members took back the right to use the "Sodagreen" name.
