"Just Because" by Joyner Lucas is a plea for spontaneity and passion in a relationship that has become too routine and predictable. The speaker reminisces about how things used to be between him and his partner, when she would strip or buy him gifts for no reason, and wonders why they've grown so distant and disconnected. He suggests calling, drinking, and having sex just for the sake of it, to recapture some of the spark they've lost. The bridge and chorus repeat the phrase "just because" to emphasize the importance of doing things for no other reason than to enjoy each other's company. The voicemail from his grandma highlights the speaker's loneliness and the need for human connection beyond the superficial. Overall, the song is a plea for more authentic and spontaneous interactions in a relationship that has grown stale.
