Rockstar is doing a VERY rare thing with radios btw. Returning music FOUND.
Just looked at the music preview. They have Slayer - raining blood as a track that will play on the metal station. Keen eye'd people will know they also had that song on vrock in 2002 in vice city. This is only the 2nd time they've added old music from older GTAs. The other time was with LSUR in GTAo where the Black Madonna plays "Joe Jackson - steppin out" as part of her set which is also another classic used in vice city. In fact it's so known my gf heard the song come on the radio when I was playing GTAo and she said "hey isnt that song from vice city?" It gives me hope
