Do we really need so many singing competitions on TV?

How many freaking singing competitions do we really need? Just gave up on watching The Sing Off and pretty close to the same on The X Factor.  I get it... we all watch but geez, how many is enough.

I love to sing... always have. I sang in an a cappella group in high school but things have really changed. Maybe it's because I'm mainly a blues guy at heart but this stuff just comes off as corny now.  Now I just sing from the heart, like here in Georgetown, SC last weekend.  So do you watch these shows? And like them?
