Filmed at the Palazzo Versace Dubai and at Domeniul Manasia in Romania, it portrays Inna in various settings, wearing a sparkling silver outfit.

"Flashbacks" was written by Elena Alexandra Apostoleanu (Inna) and Minelli alongside its producers Sebastian Barac, Marcel Botezan, David Ciente and Alexandru Cotoi.

[12][13] Dance-Charts' Manuel Probst singled the track out as his favorite song on Heartbreaker and noticed "atmospheric" sounds, a piano loop and slap bass in its composition.

Lyrics from the song include: "I'm on the road, empty and cold to a distant destination I don't know / Been thinking about you, we back in days of all / It's hard to admit it, I still miss you, miss you so" and "Flashbacks of our memories, the past is my enemy, and I'm drowning in a sad melody / Flashbacks of our memory, the past is my enemy / It keeps holding, holding on me / Come break the silence.

[22] The video switches between color and sepia scenes and shows Inna wearing a sparkling silver dress and boots in different settings—lying on a couch and in a bathtub, walking inside a hotel, placing her head outside of the window of a moving car in traffic, and frustratingly screwing up her make-up in front of a mirror.

[24] For Pro TV's 2021 New Year's Eve televised event ProTevelion, Inna performed the track live along with "De dragul tău" (2021).
