I Don't Know is by Erika, the Italian dance singer who broke through in the early 2000s with Relations before this track became one of her best known songs. Rooted in the Eurodance and Italodance scene that filled clubs across Europe, it later resurfaced online in short excerpts and compilations, including a 2007 Awesome Music listing. Because many uploads dropped the artist credit, listeners kept sharing and searching for it as an unknown mid 2000s song, which helped keep the catchy vocal hook circulating long after its first release.
