Here's the song I mentioned in the OP:

My goodness. You sure know how to pick your songs, don't you?

This is a Shia song that says some really bad stuff about Omar. You know, Omar is HATED in Shiism and in Iran in particular. No one names their kid Omar in Iran. Omar Khayyam, the poet and mathematician, gets a free pass because he was around several centuries before Persia became a Shia state.
There are a lot of stanzas in this song, including wishing that Omar's soul be damned. Also asking that Abu Lulo never tire. That's a Persian phrase said to someone who does a great service to you or work for you. Instead of saying thanks a lot, you say, "May you never tire."
Anyway I wouldn't play that thing around a Sunni who understands Persian. LOL
