Do you mean graphics as in technology or artstyle? A technology comparison would make no sense, so I'm assuming you mean artstyle, and I can't say one or the other. A good game must have both a good artstyle and good music to be good.

Graphic, music can be substituted or disable, graphic can't be change...

On second thought, you probably meant art style. In that case, still music, but just barely.

Err... Is everyone above me trolling? Because graphics are more important. If you don't like the game's music you can simply turn on your ipod and listen to the songs you think that fit better in the game.

Besides, you can play without sound, not without picture.

Music, I had my Ipod playing through my 360 whilst I was completing the Gears of War campaign mode because there wasn't any music in the game.

Graphics by far.

I do enjoy nice music in games, but hell 98% of all games have some vanilla style music that I immediately forget the second I hear them.
So with a few exceptions music is IMO the least important part in every game.
HUD layout >>>>>>>>>> music

Oh no, others have different opinions than you do! How dare they!!

good way to destroy the atmosphere

Obviously, they should thank God for not living in Portugal, otherwise I'd totally spank 'em... >_>

Man, sucks to be you if you don't feel anything hearing classic themes from games! For example, that metroid other m trailer... the best part was gameplay... but the second best part was that 5 second theme at the end! Or when the Zelda theme plays in the overworld... or when the boss theme of megaman plays for 2 seconds after choosing the robot you'll fight!

Damn, those are great moments! But graphics are good too :)
