Each week we select a theme and count down the top 40 songs that make the cut.

Make sure you're watching Saturday @ 7:30pm to find out how the songs stacked up against the rest.

Don't miss an episode txt uc40 to 2555 to receive txt alerts (txts cost 50c to stop simply txt STOP to 2555).

U Choose 40, Saturday / 7:30pm.
