The song "U Did It" by Chris Brown featuring Future is a collaboration that explores themes of relationships, personal growth, and the impact that certain individuals can have on someone's life.

In the verses, Chris Brown reflects on his experiences with women and the influence they have had on him. He refers to a woman who comes over late at night with her friends, highlighting his attraction to her and the desire for her to be ready for anything. Brown mentions getting high on drugs like Miley Cyrus (a reference to the popular party drug MDMA) and using codeine to relax, possibly suggesting how he copes with the pressures of his lifestyle.

The lyrics also touch on the idea of evolving and growing in relationships. Brown mentions a hypothetical person named Vivian and how they don't communicate as much as they used to. Despite the distance, Brown acknowledges that the person has remained true to him since they first met. He expresses a desire not to interfere with their new relationships but also hints at the tough love he has encountered due to his experiences in the streets.

The refrain, "Bye-bye, baby, goin' bye-bye," and the subsequent lines about leaving someone on the sidelines and pulling away like a drive-by, imply a sense of detachment and moving on from past relationships. Brown suggests that the woman he's referring to has found a new partner, which is evident from her having a pool and "her new guy tying the knot." This could imply that she has moved on and gotten married. Despite this, Brown reminisces about the past and how he had treated her well, living together in a luxurious penthouse, and indulging in various activities.

The chorus, sung by Future, reinforces the idea that the woman being addressed made the speaker (presumably Chris Brown) a better person. It highlights the transformative power of the relationship and how the woman's presence has positively influenced Brown's life.

In Future's verse, he echoes some of the ideas expressed by Brown and discusses the dynamics of his own relationship. He mentions the woman coming over with her friends and being ready to have a good time. Future acknowledges that he should have started hanging around the people important to his partner sooner, showcasing a desire to invest more time and effort into the relationship. He talks about spoiling her, fulfilling her material desires, and being committed to making her happy.

The refrain is repeated again, emphasizing the woman's departure and the speaker's realization of the impact she had on him. Future also mentions the engagement and how the woman read about it on blogs, which suggests that their relationship has had public attention. Despite any challenges or changes, he expresses gratitude for the role the woman played in his life.

Overall, "U Did It" reflects on relationships, personal growth, and the influence that certain individuals can have on shaping one's character. The song highlights the positive impact that these relationships can have, even if they ultimately come to an end.
