0 out of 10 off tempo songs and the lyrics are wrong

I downloaded this app to only sing one song and that is all star. Ive listened to this song a couple thousand times and i know the lyrics and tempo perfectly but when i started playing it it was going slow at fast parts and vise versa. Also the lyrics are as if someone heard the song the first time. When the song goes " the years start coning and they dont stop coming" years is replaced with itch. Also when it goes "but the meteor men beg to differ." The app goes "the media men beg to differ." That was the point where i deleted the app out of anger for completely botching the song. If you are a sensible person please dont download this app.
