Human beings who can't appreciate Johnny Cash didn't deserve to be born.
I think I love you 
You're joking right? Not everyone here is American.....country-music isn't for everyone.
Don't need to be American to enjoy the man in black plus all of his music isn't country some of his music is gospel and even rock he did covers of U2, Nine Inch Nails, Marty Robins, etc plus come on The Man Comes Around, Hurt or Gods Gonna Cut You Down is just epic.
But I did enjoy Mass Effect's music as ambient music but I wouldn't mind music appearing at shops, locations in the ship for example a crew mate playing guitar and for example in the cabin it annoyed me the only music you could play was the ambient music its not bad but there's gotta be non orchestral music around I'm not asking for the developers to imagine futuristic neo-rock music because even in the future the blues would still be around, rock would be obviously it would be a pain to get big music in the game or to write their own music and have it recorded but there's plenty of local musicans that would glady recieve a 20k fee for a few songs to be in the game.
Obviously there's a whole lot to it but I'd enjoy to see what music (besides dance) would exist in this world, I mean music obviously evolves but there's always going to be repeats of the past I mean we still have gospel music, folk music, etc. That reminds me I wish there was a mod for custom music to be added to the music player in my cabin in ME2....
