Lady Gaga Artpop Cover Lady Gaga is having her L.A. fans leak the track list to "Artpop" one by one on a mural and posting the images on social media. One by one. Like one every 10 minutes instead of just leaking the track list all together. Fantastic! Grr. Ahem. The biggest surprise? A duet with R. Kelly! Other special guests are Too Short, T.I., and Twista.... To save you time, I sat here and caught each track which took a total of 42 minutes. Click here for the track list:
