Can someone plase transcribe this Bulgarian rock song?

The bits I can understand:

Az sum Bulgar4e, obi4am!
Na6te planini zeleni!
Bulgarin da se nari4am!
Purva radost e za mene!

or

Аз съм Българче, обичам!
Наште планини зелени!
Българин да се наричам!
Първа радост е за мене!

It's a patriotic poem, written by Ivan Vazov.
I'll translate the whole poem lately, now only this couplet:

I'm a Bulgarian! I love
our green mountains!
To name myself a Bulgarian -
It's the best joy for me!
