Well I haven't found an answer to your question yet-only found this paragraph:
On an interesting note, Ja Rule stars in that Steven Seagal movie and the trailer features are by DMX. Yet, aren't the producers aware of the battle going on between the Dog and Mr. "Between Me and You?" So I pop by my local record store and examine the CDs. I already have all of the songs off Half Past Dead.
My guess it's "Angel"......being that is the last song listed in the credits and credits "usually" list songs as they appear in the movie......however there appears to be a couple of refferals to "Parrot" in the track listing ..which maybe a group
PS: I or someone else can record it from DVD and post it for download if you'd like a copy of it.....
I just watched the movie at TV and I recognized that song at the end...I started to search at the web but after, I guess, now three hours of searching I havent found an answer who performed that song, maybe after 8 years anybody knows about this
