Twitter: @YungHeir @Djsuperstarsmit Yung Heir links up with DJ Smit to host his newest release for his song "Couldn't Be My Old Self!" The song talks about Heir switching up because how he was before doesn't truly show who he is... Heir also uses a mixture of rapping and singing with his flow instead of just doing a straight flow with a hook which gives this track a nice switch up from what you usually hear.
