Seema's song selections and their renditions are perfect. Successfully trying different genres of songs only proves how meticulous she is.
If she gets out, it will be purely because of the least number of votes (as designed by the format of the show). It will only mean that the voters loved other contestant/s more on that day. There is no one to blame (unless one is desperately looking for someone to blame).
Relating Seema's song selection (and not her actual singing skills) to her staying in the competition is as absurd and bizzare as relating Mother Teresa to a crime.
