Question about pronunciation
Hello everybody!

I have a question that is killing me (for a long time actually).

In the song "Wait" by M83 there's a line that says:

"There's no end, there is no goodbye", they are clearly singing with a "S" sound instead of the regular "TH" sound, is it common for native english speakers? Was it just to fit in the song?

Please correct any mistakes I have written.

Thank you,
Fernando Bueno

I have a question that is killing me (for a long time actually).

Answer

I mean, there is a simple answer here. The singers are not native English speakers. M83 are a French band. The 'th' sound does not exist in French. Hence the mispronunciation. Some native English speakers in part of England pronounce 'th' as an 'f' sound but as a 'z' or an 's', no. These are pronunciations by native speakers of other languages.

Answer

Fernando-  That is only for the sound of the song.  I have never heard anyone pronounce  "th"  with a "s" sound  in any word.   
Your English is fine.  -S
