Yep. SINGLE PLAYER DLC. I'm impressed.
Not quite, They only added the Radio Station none of the new cars or any of the vehicles or weapons have been released since PC came out are in Story Mode either
Yes quite. The literal definition of DLC is Downloadable Content.
Is this content? Yes.
Is it downloadable? Yes.
It may not be the story mode expansion many were hoping for in 2014, but it's still new content available in Single player. I'm impressed that, even if it just music, Rockstar added something new to the single player experience after 3 years of neglect.
Wanna bet it was accidental?
and it was easier to just left it in then to figure out a new way to add music to online without automatically adding it to sp as well.
