So, both Beyonce (as a solo artist) and Lady Gaga have had massive careers, with hit after hit, multi-million dollar marketing campaigns, huge shows around the world, etc. Beyonce has released 4 albums, Lady Gaga 2 and an EP. Beyonce has 5 #1s while Lady Gaga has 3, but Lady Gaga has two 6+ million selling digital songs alone... My question is, who is the biggest hit-maker???
