With the duration being about 4:13, this song is close to the average duration of a typical track. Since Proof only contains only one song in the album, we like to consider this song as a single. In terms of popularity, Proof is currently not that popular. The overall tone is very danceable, especially with its high energy, which produces more of a euphoric, cheerful, or happy vibe.

B Minor is the music key of this track. Or for those who are familiar with the camelot wheel, this song has a camelot key of 10A. So, the perfect camelot match for 10A would be either 10A or 9B. While, a low energy boost can consist of either 10B or 11A. For moderate energy boost, you would use 7A and a high energy boost can either be 12A or 5A. However, if you are looking for a low energy drop, finding a song with a camelot key of 9A would be a great choice. Where 1A would give you a moderate drop, and 8A or 3A would be a high energy drop. Lastly, 1B allows you to change the mood.
