Here are the lyrics (I interpreted them so some parts are not accurate and I couldn't find any reference to cross match)

Time is my enemy
and it's taking you very fast from me
as the seconds fade into deathly days
I'm falling in my lover's summer tree

Pick up your black box
place me inside
you wont think you ve known me at all
until for you I cry

Hands on the soundless box
choking time with all their silent gleam
they have won and I can [bad word] from all the signs they tell my eyes to see

Pick up your black box
place me inside
you wont think you ve known me at all
until for you I cry
