The fact that she blew it so badly does give some credence that she doesn't normally do tracks and was completely unprepared to deal with it. The fact that she then turned around and blamed it on the band shows how unprofessional and undeserving of what fame she has had up until now.
Whatever she does have is strictly manufactured and a result of other peoples work and access because of her sister. I have no issue that she got breaks and access because of that, it's the nature of the business where success more often than not is a lucky break as opposed to talent and/or hard work. At some point though you have to earn it and clearly she has not and given how she reacted is unlikely to.
Nor do I have problem using tracks to supplement your music. We do it all the time and all our vocals are samples on a computer and it takes two dub pscientists with Imacs, samplers, keyboards and patch panels to produce our background music and lyrics. And what happens if it all crashes or the power goes out? We don't miss a beat and power through strictly with percussion.
Yes performing in front of a live audience is hard. And I daresay few other bands work as hard as we do. Depending on the situation we bring in and build our own stages, sound system, monitors, power, lighting, aerial and instruments and then clean up and tear it down afterwards. And playing clubs and other venues has it's own share of problems. Faulty equipment, untrained personnel, bad systems, surly union guys more worried about their next break.
Almost any band would absolutely kill to have an opportunity like SNL. To be given an opportunity like that and then handle it so unprofessionally to me is practically criminal.
