I've been meaning to download this mixtape for quite sometime now, but being out of the country and perpetually busy has delayed that process. JJ is an ill swedish band that made the song Ecstacy (which sampled lil wayne's Lollipop). Anyways, they do some sick rap samples/covers in their albums (check out this cover of My Life by the game & lil wayne), and this mixtape is just filled with them. They seem to have a liking for weezy samples which is fun to hear. Check out this wiki link to see their sample list for each song, although it isnt too tough to figure out by ear.
The title for this album is interesting too:
"the expression Lil Wayne used in the trailer for his mixtape No Ceilings. Wayne mentioned that when making a mixtape and sampling other artists, he doesn't kill the artist in question, he Kills their song"
