Hey Edu - That's a hit! Don't give it away.

As I hear it, the voice is still hard over on my left, although on this newer version I can hear that there are two vocal tracks, the one on my right is still barely there. Sounds like about 30% R.

Maybe you could duplicate the strong Left track- same settings- same everything, but put it hard Right.
After that duplicate it again, but center it.
Raise the volume of the center vocal & add a touch of chorus.

Kjaerhus makes a great set of free plugins, chorus being one of them.

If you want pops & crackles there are VST's which do that job, but go easy, 'cause it's easy to be cheezy.

Try 'Audio Impurities Vintage Ed'.

Whether this helps you or not, I wish you well.
It's a nice little song

Thanks
