The tension between Meek Mill and Cassidy has been building up on Twitter for a few of months now. A rap battle was supposed to happen but Meek decided Cassidy wasn't "hot enough" for him to battle. Cassidy responded with a diss track called "Me, Myself & iPhone." In the song he said Meek released "I'm A Boss" because he was riding Rick Ross' coat-tails and that all of his songs sound the same. Meek went on Twitter and said Cassidy possibly snitched on his co-defendant in his 2006 murder trial by taking a plea deal and was locked up in protective custody then officially challenged him to battle! Who do you think would win between the two rappers in a battle, Meek Mill or Cassidy?
