Many people asked for this, so i went ahead and made this small modification that replaces the radio stations in Liberty City and Vice City with the ones present in VCS and LCS. Sadly the only station that i didn't add is Radio Del Mundo from LCS.
I did give a link to this a few months ago but it was in the main thread, so i reckoned i'll make a new thread so it'll be easier to find for new users.
Some of the icons were already present in the radio.txd file but i also made a few new icons. (which are kinda bad because i suck at photoshop)
