Me & U (Cassie song)

"Me & U" is a song by American singer Cassie. It was released on April 25, 2006, as her debut single and as the lead single from her self-titled debut album (2006). Written and produced by Ryan Leslie, the song reached number three on the Billboard Hot 100 and remained in the chart's top 40 for nearly five months.

The song's "Bad Boy" remix features Diddy and Yung Joc and the song's "The Inc" remix features Ja Rule and Harry-O. The single became a top-three single in the United States, a top-five single in New Zealand, and a top-10 hit in France, Ireland, and the United Kingdom. The song was considered "a slinky, vintage-sounding track with a hypnotic, snake-charming whistle," and likened to imitating Janet Jackson. The song is performed in the key of G♯ minor with a tempo of 100 beats per minute.

The single received two platinum certifications from the Recording Industry Association of America (RIAA): one for sales and streaming figures and one for mastertone sales. It was also certified double platinum by the British Phonographic Industry (BPI).
