The Tongue Kissin' that you have linked is nice quality, but there's no bassline on that version. The Free 2Pac has a bassline, but it's not as good as far as quality on the other parts of the song (vocals, highs etc.). There was a 31 second clip floating around here when this was first leaked that sounds better than the Free 2Pac version and the " - Thug Tears - dat ripp 04." That quality in full hasn't been leaked yet. (at least publically...

)
here's a comparison of the three different versions:

1st clip = the first clip that was available
2nd clip = free 2pac version
3rd clip = the "320" rip
i edited the last two so they would be at the same point in the song as the first clip. Yes, the "320" rip sounds almost exactly the same, but like i said above it has no bass line. Listen on a good stereo and you'll notice the difference.
i would love to get the full version of the first clip...
