A lot or a little?
Parents need to know that this recording app uses auto-tuning, first widely heard in Cher's 1998 hit, Believe. Auto-tuning corrects pitch and adds a distinctive warble to the voice. That's cool. What's not so great is the trashy rap music of 35-year-old Faheem Najm, aka T-Pain. The lyrics are smutty and demeaning to women. The app features profanity, sex, and drug references.
