Larry Page is moving fast to build his search giant’s street cred in the rapidly growing music streaming business. Page’s Google is in talks to acquire the 6-year-old Songza, a Long Island City-based music curation and streaming service with 5.5 million active users, two sources told The Post. Music curation — how a subscribers’ songs are chosen — is the hottest, most competitive front in the music streaming wars. Songza competes with Pandora, with its 77 million active users, and Spotify, which recently hit 10 million active users. “Google is offering them around $15 million, the question is, does Songza take it?” said one source close to the conversations. The offer seems puny when placed next to Spotify, which has a $4 billion valuation, and Pandora, which has a market cap of $5 billion, sources noted.
