Key! has been busier than ever over the last few months by dropping countless amounts of material. Today, Key! continues to grind despite the successful release of his recent mixtape FKEYi featuring exclusive production from FKi. The new song we have just received is titled 'Tighten Up' featuring Wavy Wallace. According to information on Key's Soundcloud, it appears that these two have more work in the stash. Stream 'Tighten Up' above and make sure to check out FKEYi here if you haven't already.
