In the vast and fast-growing world of Internet radio, the Foster City company is everywhere, with some 5,000 stations and 3.5 million listeners. [...] when people talk about online radio and music listening options, it’s all Beats and Pandora, Deezer, Rhapsody and Rdio, Slacker and Songza, iHeart, iTunes and TuneIn. Anyone — music fans, musicians, companies (including radio stations) could connect with Live 365’s technology and tools and go on the air — on the Internet, anyway — for a modest monthly fee. The business model — of offering mostly channels operated by non-professionals — may be another reason Live 365 is rarely in the conversation about online music services. [...] dialing around recently, I ran into an old-time radio station that displayed a photo of Nat “King” Cole and a song title, all while an unidentified drama played. Another station, promising holiday music by “crooners,” mixed Sinatra and Michael Bublé with Celine Dion and that notorious Rat Packer, Kate Smith. That’s one of the beauties of Live 365, which offers some 260 music genres from stations in 150 countries. [...] according to Dennis Constantine, director of broadcasting, stations run by real people are a draw, with the most popular ones attracting some 20,000 listeners a day. While others offer music libraries and stations based on computer algorithms, he said, We provide music curated by human beings. Having weathered storms in commercial radio, Constantine appears content at Live 365, where he is recruiting more artists and celebrities to operate stations (David Byrne, Pat Metheny and others are on the air). [...] he is best known as the program director who enraged Howard Stern so much at WNBC in New York in the early ’80s that Stern included him in his autobiography, “Private Parts,” as “Pig Virus” and, later, in a movie, as “Pig Vomit.” New Bay Area Radio Hall of Fame inductee Celeste Perry is a member of Broads in Broadcasting, not “Babes,” as I mistakenly typed.
