Call My Name was available as a promotional single from the album Musicology (the third single overall), available in Fall, 2004.
A few months before the promotional release, however, Silver Tongue (Demo) was released on the NPG Music Club Musicology Download Store as a "virtual b-side" to Call My Name, although Call My Name itself was not available as an individual download, and no promos were sent out at the time.
Although Silver Tongue (Demo) was not included on any release of Call My Name, it is included here for clarity's sake.
The single reached position 75 in the US Billboard Hot 100 and position 27 in the Billboard Hot R&B/Hip-Hop Singles charts. It also received a Grammy Award in 2005 for Best Male R&B Vocal Performance.
