10 Beyoncé songs that should have been released as singles

1. Beyoncé - 'New Shoes (Postcard)'
This song is interesting, as not only was it not released as a single, but it wasn't even released on an album. The song is from Beyoncé's 'B'Day' era, and sounds remarkably similar to 'Irreplaceable.' Some say it was the original version before being modified and eventually becoming 'Irreplaceable' and some say it acts as a 'Irreplaceable Part two' - either way it is just as infectious as the hit single.
