Written by Marc Lennard and Achim Heider under his pseudonym JoHo HF, the Christmas song was produced by frequent collaborators, duo Kay D. and Rob Tyger.

A midtempo love song, the instrumentation includes bell chimes and harp sounds.

The song's lyrics declare that the protagonist wants for Christmas to be united with her lover and family for the holidays.

The song replaced Melanie Thornton's "Wonderful Dream (Holidays are Coming)" in Coca-Cola's Christmas promotional campaign throughout German-speaking Europe.

Commercially, "The Best Side of Life" peaked at number four on the German Singles Chart and reached the top twenty in Austria and Switzerland.
