Most of the songs they sing are bad enough in their original version. Who thought it would be a good idea to have pre-pubescent 9-year-olds cover them??? Not only are the children of Kidz Bop not very good singers, they cover some really inappropriate songs for their apparently "family-friendly" albums.
Here's a graph that I'm sure is backed up with real scientific evidence proving why Kidz Bop is such a ridiculous phenomenon.
Kidz Bop has been around for 15 years (how old do you feel?) and in that time, they've made some pretty awful covers. Here's just a few of them. Make sure to listen closely for the inappropriate lyrics they've changed to make the songs kid friendly.
"Before I leave brush my teeth and then I go and pack."
"Walk up to the club like whattup I have a hit song."
"Can't stop now more mints let's go!"
For a more PG-13 version, insert "shots" for "mints"...
They just took out everything except the chorus here because nothing LMFAO has ever said is kid friendly.
