Spotify, the largest online music streaming service, has launched a new technology test to block songs with offensive and rude lyrics.

The new technology began on iPhones and iPads, after six years of demand on its online forums.

But some of his employees told that the new technology did not have enough protection.

Competitive applications such as Apple Music employ techniques that use passwords used by parents so that young people do not listen to pornographic words.

Since 2011, music and online music applications have had to write a “rude” word to songs that music companies believe are inappropriate for children.

Nicola Ford, a mother of children, started an online petition demanding a way of screening lyrics after listening to songs.

“I was exposed to some embarrassing situations when the children were listening to some songs on the radio and then suddenly our house was filled with sobbing words when they played the same song through Spotify,” she said.

“I started a petition on the Internet and found that many parents are asking for the same thing, so the petition has attracted a lot of attention,” she said. The new amendment, introduced in April, prevents songs that contain raw words from being played, but does not replace them with “clean” copies. Nicola says that is not enough.

“The children want to listen to the song they listened to and that’s why they’ll try it one way or the other,” she said. “If they listen to the song, I’d like to listen to the clean version.”

Others complained that the new option, which is available only to users of premium services, does not contain a password and anyone who uses the device can change it.

“It would be useful for the owner of the device, ie the parents of the children, to have control over the device,” Nicola said.

“These companies must strive to help us control what we are working in our homes, including Spotpay, I think they should have paid attention to it before.”

Spotify describes the new technology as a “test version” and is being tested by “some users”.
