Here's some info on all the songs mentioned in this post:
1 - X.M.I.X. by Navjot Singh Kalsi. Kalsi is a friend of mine from Punjab. He's just another guy trying to produce tracks, so the Kaka track is not his own release. It is definitely going to be released by AMX.
2 - Jaroorey Bankeh - As stated above and in earlier posts, it's by AMX. Probably on Kaka Bhainiawala's solo album.
3 - Nack Ke - Kaka Bhainiawala by Tru-Skool. Here are a few posibilites:
1 - Someone took the sample vocal and remixed it with the Nack Ke track from Repazent (Nach Ke by Jaswant Heera. Music by Tru-Skool)
2 - It was produced but hasn't been released becuase it is part of the solo album by Kaka B.
3 - It was a track that was produced, but never was released or will be released because they feel it's not good enough for a release. If you read JK's interview over at Chakdey.com, he tells how Tru-Skool and him have produced many songs, but they will never be released because they (Tru-Skool and JK) feel the songs are't good enough to be released.
4 - Jaan Toh Pyaari by PJD - Yes the promo is real. Word is confirmed. PJD is going to be releasing it. He played it at an event. It sounds much better than what JR-Dread did to it, in my opinion.
Here's the clip:
