Good news, bad news for Nashville ...
The good -- Justin Timberlake's now officially on board with a plan to bring an MLB team to the city!!!
The bad -- it still appears to be a massive pipe dream.
JT announced Wednesday he's joined on with a big investment group -- headlined by businessman John Loar and ex-Red Sox GM Dave Dombrowski -- to attempt to get Nashville its own MLB team.
The plan sounds amazing on paper ... the group of investors wants to build a new stadium in the downtown Nashville area and have an MLB team playing in it by 2024.
