Unidentified clandestine on 4025kHz

I heard a clandestine station on 4025kHz at 0030UTC last Thursday night, with long segments of Middle-Eastern pop music and announcements "Radio Farda". It's clear that it's not the US one, but another clandestine. Which station could it be? Any ideas are much appreciated. "Voice Of The People Of Kurdistan", "Voice of Iraqi Liberation" and "Patriotic Union of Kurdistan Radio" used to broadcast on this frequency years ago, during the war in Iraq... 73!
