He meant the "aye aye" sound from Project One - Rate reducer (Headhunterz remix). BTW the main vocals remind me of the good old Qlimax 2003 and Pavo's set when he dropped the mighty Dj Rezonanze vs Dj Reezer - are you ready. OWYYYYYEAAAAAAAHHH
ReVerseMusix Pandora was much better or even his old soundset from Red Planet. The kick here is ok, but that bass is weak. I listen to this track with my Beyerdynamic DT770 Pro Studio headphones and I can tell you, that I'm disappointed with that.
