Everyone has his or her karaoke standby. (Please don't tell us yours is by Celine Dion.) But every once in a while, it's important to inject some variety into your same-old, same-old routine. Enter Pocket Karaoke (Simon Spotlight Entertainment, 2008; $9.95) by Sarah Lewitinn, a DJ and founder of the record label Stolen Transmission (she's also known as influential indie-rock blogger Ultragrrrl). The book includes karaoke song lists sorted by artist, genre, occasion (we like "Songs That You Probably Shouldn't Sing Unless You Want Someone to Think You're a Wee Bit Slutty"), and celebrity. Who knew that Gideon Yago could be coaxed into belting out "Like a Prayer"? Lewitinn also notes key points like the minimum number of drinks required to perform one artist's work versus another's.
