Since being sign by a label from doing grime, Chipmunk has begun to get noticed all over the world by doing songs with maybe people such as Trey Songz, Keri Hilson, Chris Brown and many more people. He hasn't done a lot of Grime since that signing, and he has started off songs with a more Rap flow, but today Chipmunk released a freestyle called 'Hustle Hard' which is a cover over Ace Hoods hit song. On the freestyle he goes hard, and he uses a faster Grimy flow. It's something that all his Grime fans love to see, but we still need to see more Grime from him ! It's a good effort, and I like it.
