Songtext sind nicht synchron

Hey Deezer,

I really like your service and i use it for more a long time now.

There are some problems concerning lyrics. Sometimes they won‘t move along with the song, sometimes they play in a wrong speed, so they won‘t match with the song. Additionally the lycris are not displayed that well, which would be important for karaoke sessions. Unfortunately i have to say that Apple Music is doing a lot better in this concern. 
Are there any plans to improve the functionality and the design of lyrics?
