Your heart is hurting. So the last thing you need is to listen to sad songs of love lost, played on a plaintive little ukulele by none other than Eddie Vedder. Has he no mercy? Still, you take in every note, every word on his new album, “Ukulele Songs,” and then settle in to talk with Vedder, admitting you’re a bit of a mess. “You really heard the record then,” Vedder says, kindly, and then suggests you buy a ukulele and try to strum the soreness out of your soul.
