Ah the sweet memory this brings. When having no internet at home (at around 2004), sending the songs from my mobile phone to the computer via bluetooth, and listen to the music in GTA Radio while raining outside!
Copying songs to gta sa userfiles, will incrrase size of the folder. No need to waste hardisk space. Just make a shortcut of your music folder and cut and paste that shortcut folder to gta sa user track.
Hope you understood.
