Lady Gaga set for No 1?

Lady Gaga could be on course for a No 1 this Sunday (May 15th) on The Vodafone Freebees Big Top 40.

She's currently (12.05) at No 1 on the iTunes chart with "The Edge of Glory".

Last week David Guetta and his mates Flo Rida and Nicki Minaj went straight to number 1 with “Where Them Girls At”.. but will it be a short lived reign at the top?
Bruno Mars came close once again with “The Lazy Song”.. could he make it to the top spot this week?

And then there's Take That who have released a brand new track this week. Love Love features on the soundtrack to the new X-Men movie.  Will their army of fans get them to the top of the chart?
