Even though the music is 100% greek and i am fluent in greek she is singing in bulgarian. English lyrics are below.
(The word OPA is greek for hey, not like we say in english "hey you" but more like a loud exuberance of the word 'HEY")
After more research I have found out she had a greek producer for this song thats why she incorporated the greek music and the word opa.
Enough of me blabbering here is the song translated to english.

"Kiss me

C’mon …opa opa opa opa…let me hear it once again
C’mon….opa opa opa opa…I won’t save you this
C’mon….opa opa opa opa…c’mon touch me
C’mon….opa opa opa opa…here I am ,kiss me

I want the same – it’s nice with you
You have all my body

To catch me again
To feel me again
To give all myself up
To surrender myself to you

C’mon …opa opa opa opa…let me hear it once again
C’mon….opa opa opa opa…I won’t save you this
C’mon….opa opa opa opa…c’mon touch me
C’mon….opa opa opa opa…here I am ,kiss me

You want me breathless, you want my taste
Keep me for long ,as it has been not only for one time
I want more and everywhere
I want my lips to hurt from you"
