This is the reason why the music industry is no longer beneficial. People who actually sing are forgotten and "singers", if they are, such as Katy Perry are still performing. Ridiculous!
I wonder what songs will be in Gaga's tribute. I mean, Space Oddity / Let's Dance / Heroes seem pretty guaranteed.
But Starman, Ashes to Ashes, Changes, Fame, Fashion... Lazarus? ... and so many others could be fit in as well. I guess it depends on how much time she's getting and how much of each song she wants to sing.
