Second CD by Maroon 5 Faces Great Expectations

Even an ardent fan could be forgiven for wondering just how Maroon 5 would sound on “It Won’t Be Soon Before Long,” the follow-up to its wildly successful debut album, “Songs About Jane,” from 2002. After all, on its long journey to stardom this band abandoned its post-grunge roots for a radio-friendly pop-soul sound, even while dabbling in hard rock. (At the height of its success from that first album Maroon 5 closed live shows with a cover of AC/DC’s “Highway to Hell.”)
