"Tell Them" is a song by James Blake featuring Moses Sumney. The song explores themes of solitude and self-discovery. The lyrics suggest that sometimes it's necessary to be alone and let go of negative influences in order to grow and find one's purpose. The line "In life, just be alone, though you're a wanderin' soul // And you got to move on from the squandered soil" emphasizes the idea of leaving behind toxic or unfulfilling situations. The song also touches upon the fear of staying in a negative environment for too long. The line "In the snake pit so long, I've got posters up // Been defending so long, I don't know how to stop" implies a sense of being trapped and constantly having to defend oneself. Throughout the song, there is a recurring theme of the heart guiding one's decisions. Lines like "Heart, tell them what you came for" and "Heart, tell them what you've been daydreamin' about" suggest that the heart holds the truth and desires that should be pursued. Overall, "Tell Them" portrays the struggle between staying in a familiar but unfulfilling situation and taking a leap of faith towards something better. It encourages listeners to embrace change and listen to their heart's desires.
