“How Long,” the second single from Charlie’s sophomore album "Voicenotes", sees Charlie apologizing to a girl for being unfaithful. Charlie teased the track on social media in the week leading up to its release, and posted a video of the voice note behind the track the night before it came out. In an interview with Ryan Seacrest released the day after this song dropped, Charlie discussed the similarities between this track and his previous single, “Attention”: With the theme of ‘Attention’ kinda being a ‘bass’ song, I didn’t want it to be, like, a ripoff of ‘Attention,’ but lyrically, the song is like part two of ‘Attention,’ as far as the story goes. I’ll leave that up to interpretation. As of the week of Feb. 2, 2018, “How Long” peaked at #21 on Billboard’s Hot 100 chart.
