Your mum is right.

Wagner is more of a joke-act sort of 'so-bad-he-is-good' nutter favourite.

Cher is also terrible but is mistaken as a legitimate contender by teen girls and then that is only encouraged by judges who see a perfect recording artist who can be auto-tuned and make 100 takes into 1 good one (with enough tweaking).

Well.. maybe that is too much for your mum but good on her for having a good sense and good ear.
