It takes a lot to be honored with a Boston Music Awards Song of the Year nomination. There must be a local angle and a universal appeal. Ideally the song should be emotive, well-crafted, lyrically poignant and instrumentally sound with a staying power that lingers in the minds and hearts of the listeners for years to come, but realistically the ultimate say remains in the hands of the nominators and the voters. With that in mind, we bring you this year’s nominations for the BMA’s Song of the Year. Each is very different in sound, style and message, but has justly earned its way into the category for the locals to vote upon.
