3

The song '3' by Glee is a playful and provocative exploration of non-traditional relationships, specifically focusing on the concept of a ménage à trois. The lyrics repeatedly emphasize the numbers 'one, two, three,' symbolizing the inclusion of a third person in a romantic or sexual relationship. This idea is further reinforced by the playful reference to 'Peter, Paul and Mary,' a famous folk trio, suggesting that three people can harmonize together just as well as two.

The song's chorus, 'Not only you and me, got 180 degrees, and I'm caught in between,' highlights the complexity and excitement of being involved with more than one person. The phrase '180 degrees' suggests a complete turnaround from traditional one-on-one relationships, while 'caught in between' indicates the singer's position in the middle of this dynamic. The repeated question, 'Are you in?' challenges societal norms and invites listeners to consider more adventurous and unconventional forms of love and connection.

The lyrics also touch on the theme of living in the moment and embracing fun without overthinking the consequences. Lines like 'What we do is innocent, just for fun and nothing meant' and 'Living in sin is the new thing' suggest a carefree attitude towards relationships and a willingness to break free from conventional moral constraints. The song's upbeat tempo and catchy melody further enhance its playful and lighthearted tone, making it an anthem for those who dare to explore the boundaries of love and intimacy.
