I might as well ask some of you how is Katy supposed to be ''eligible'' of holding a residency when she barely released about 17 singles in the US (from which 13 are hits), while Gaga released about 15 singles (from which 11 are hits.

The ones that I wouldn't count as ''hits'' for Katy would be: TOY, Uncle, Birthday and TIHWD
The ones that I wouldn't count as ''hits'' for Gaga would be: Judas, MTN, DWUW and GUY
