If you're a fan of Slayer and have an Android phone, you're in luck. Sony Music has released the Slayer app for Android, and it's really good. And loud. And evil. You'll find everything you ever wanted to know about Slayer at your fingertips, including show information (with a quick link to buy tickets), the full discography, news, weblinks, and a fanwall for commenting and leaving photos. On the multimedia side, you have a well rounded list of tracks that play right from the app, as well as plenty of concert footage in the form of mobile optimized video.
Besides being a feast for the senses, the Slayer app has some social media functions as well. Not all death metal fans are anti-social, so the app gives quick ways to share via SMS or Twitter, and is integrated with Foursquare for concert venue check-ins.
Even if you're not a fan of Slayer -- and you really, really should be -- you have to appreciate the polish and thought that went into this one. It's done very well and would be a very nice format for other apps of this nature to follow. If you are a fan, the download link and a bunch of screenshots are after the break.
