Milwaukee rapper IshDARR is focused on being great, and he has no time to dwell on moments that could set him back from that pursuit. “Never get bothered about things you can't change, rather work to improve the things you can change," the rapper told Complex.

That mindset is evident on his new song "Critical," where IshDARR raps about shaking off those who doubted him while staying true to who he is. "But if I hold my tongue, now that ain't honest is it/Gotta be timeless wit it, gotta know God could end it," he spits over the Take a Daytrip and Trackside-produced cut.

Check out "Critical" below and grab the song when it arrives on iTunes and streaming services Friday (May 25).
