2. Gloria Gaynor 'I Will Survive'
Gloria Gaynor's 1979 smash is one of pop's most enduring tunes. The sound may be very much rooted in peak-era disco, but its sentiment about self-belief and triumph over adversity is evergreen. Seriously, just try to imagine how many times this song gets sung at a karaoke bar in any given week. The mind boggles!
