Thank you so much, I was checking the stems, sometimes I use Acapella of a singer to produce a new remix like this one :

but this was a short time production like only 2 days, I sometimes like to add new notes and even different chords to the song. for example adding a middle part which is separated.
sorry I didn't mean to advertise my work here :D,

I liked both versions , 90's music is always the best, I love most of the bands from back then.

I think Lorde couldn't made that song's cover good, if there was not that production behind it :D , but its became good and in my idea I can say that music production is really great.
