Pitch correction software specifically for vocals that makes up for a lack of natural singing talent. 90% or more of all "professional" recordings use this software.
An extreme example is that horrific Cher song from a few years back, and the Kid Rock song where is voice is all fucked up. Used in moderation it can hardly be heard except by a trained ear.
Remember before autotune, when singers could actually sing?
Man, that chick sings so bad not even autotune can fix it.
