Must have Music Player
Finally an open source mp3 player for GTA5 free roam, RP, sandboxing, which basically eliminates need for self radio or complement's it thanks to @JustDancePC .
Now you can select your music from a menu, by artist or by album, and listen to your favorite tunes in or out of the car.
You decide what folders and music you want. Put them in your scripts folder. Then select and play your music from a familiar style menu.
Highly recommended and 5 star.
