What makes How Come by D12 notable?

'How Come' reached number 15 on the Billboard Hot 100, solidifying D12's presence in the mainstream rap scene. The song's candid exploration of friendship and loss resonated widely, leading to critical acclaim and discussions about mental health within hip-hop culture. Released on June 8, 2004, 'How Come' was a significant single from D12's second album, 'D12 World.' At this point in their career, the group was still riding the wave of mainstream success following their debut album 'Devil's Night' (2001), which had established them as a notable force in hip-hop, primarily due to their association with Eminem.
