Mystery to Me is the eighth studio album by British-American rock band Fleetwood Mac, originally released in October 1973. This was their last album to feature Bob Weston. Most of the songs were penned by guitarist/singer Bob Welch and keyboardist/singer Christine McVie, who were playing a major role in edging the band's sound towards the radio-friendly pop-rock that would make them highly successful a few years later. Although the album only sold moderately and produced no hit singles, "Hypnotized" did become an FM radio staple for many years. In the wake of the Buckingham/Nicks led line-up's success a few years later, it achieved Gold status in 1976.
