As a huge batman fan I immediately downloaded the theme as soon as it came out. After having it on my PS3 for awhile now, I still really like it. Although the sounds can be cumbersome at times it still is a really cool theme. I would still recommend it to any batman fan. Cool game by the way as well.
I'm actually not a huge Batman fan, but I love his rogues gallery. I love the theme, but wish it came with more wallpapers. There are so may great characters, why make a Batman and a Joker theme, when they could have just made an Arkham Asylum theme? I still like them both, just wish they'd consolidate.
And if you dont have a mute button theres always the turn key pad tones off. i like the Joker theme sinister yet fun with the florescent green writing but the joker's laugh is loud and comes out of nowhere... i maneged to scare my mum with it lol
