"I Don't Know" is a song by Joanne, which was released as the sixth and final single from her debut album, Do Not Disturb.

"I Don't Know" is built around Joanne's boyfriend who had moved away after one year of being together.

His career had to take him to another state, and although Joanne was genuinely pleased for him, the thought of being away from him made her heart ache.

Joanne poured all of those feelings into writing "I Don't Know", and hearing it completed on her debut album reminds Joanne of the day she had to say goodbye.
