In 2017, lead vocalist Tanzir Tuhin became embroiled in controversy, and left the band on 7 October. "
I'm Tanzir Tuhin leaving Shironamhin for personal reasons, but not the song", Tuhin said on social media Facebook.
In 2017, Sheikh Ishtiaque joined as the new vocalist.
At the moment Tuhin left the band, vocal went through the process of searching for the title through multiple headless auditions.
The band selected Ishtiaque by recording their title "Jadukor" with two different vocals.

In 2017, Tuhin formed a new band named Avash.
According to the 2019 Copyright Office, the founding member of the group, Zia, was the lyricist and composer of Shironamhin' songs.
In that case, there is a legal obligation to perform the songs without permission.
In August of that year, Tuhin ignored the Copyright Office's ruling.
Shironamhin filed a complaint in court in August.
The court legally barred Tuhin and his band Avash from performing Shironamhin' songs.
Avash later appealed against the verdict.
On 21 October 2019, the High Court stayed the ban on 49 songs of the band for six months.
As a result, Tuhin and his new band Avash were able to perform songs by 2020.
Later, in the light of the same law, the band re-appealed to the High Court and on 20 January 2020, the band won the case on their behalf.
