Written by Thomas "Orup" Eriksson and produced by Anders Hansson, "Lena Anthem" is a disco song with synthesizer instrumentation and interpolations of Philipsson's 1987 single "Dansa i neon".

[2] The two started working on the record after she won Melodifestivalen 2004 with "Det gör ont", which advanced her to the Eurovision Song Contest 2004 in Istanbul, Turkey, where she finished fifth in the final.

[5] In an interview for TT News Agency in August 2004, Philipsson revealed that "Lena Anthem" was a contender for the album's third single, although it had not been decided yet.

[12][14] Parts of the production sample Philipsson's Melodifestivalen 1987 entry "Dansa i neon",[14][15] for which Tim Norell received music credit.

[11] In the chorus, she sings "Mitt namn är Lena och jag tänker inte va' tyst / Jag tänker inte bara sitta här och vänta på att bli kysst" ("My name is Lena and I won't be quiet / I'm not just going to sit here and wait to be kissed").

[21] Although the statement was described as an "attack" in the media, Philipsson clarified that the lyrics did not patronize Lund and Nilsson; she stated that the song was about herself and that the singers were mentioned in a humorous matter.

[24] While reviewing the parent album, David Stark of TT News Agency commented that Philipsson exudes confidence throughout the record, which he felt was the most evident with "Lena Anthem".

She praised its mixture of girl power themes and tongue-in-cheek lyrics, writing, "It's fun but not silly, smart but uncomplicated, glamorous but casual.

The critic wrote that the song includes both provocative cockiness and disarming humor, which they felt signaled a big step from the Bert Karlsson "schlager factory" she originated from.

[26] Dan Backman, writing for Svenska Dagbladet, compared it to Philipsson's previous singles "Det gör ont" and "Delirium" and stated that it is "obviously intended to contribute to the singer's status as a gay diva".

[15] He wrote, "The lyrics not only proclaim Philipsson a step ahead of her rivals, but actually dare to name them, making the song not only one of the most irresistible hits of 2004, but also one of the funniest.

[31] "Lena Anthem" debuted at number five on Svensktoppen, a key chart for Swedish-language singers based on jury votes,[32][33] on 28 November 2004,[34] after being a contender the week before.

[23] She performed the song as a duet with Swedish Eurodance musician E-Type while participating on the second season of Så mycket bättre, which aired on TV4 in December 2011.

[43] Philipsson included the song as part of the encore of her 2011 krogshow [sv] "Min drömshow – 25 år som artist", staged at Cirkus in Stockholm to commemorate her 25 years in the music industry.
