I truely and honestly doubt that Alanis did a collab with Pac.
Frankly, she is white; what is she doin in Pac's area in Cali ( i doubt if the song were real it would be pre-deathrow), what is she doin near deathrow?
Where would pac find time, between trying to finish unfinished tracks and making new ones at an extreamly fast rate, find the time to hook up such a collab, or was Alanis just in the neibourhood at the right time?
Also, unless Pac didn't ACTUALLY record the track with her, how would Pac have the patience to wait for her to make up a verse????
In that respect, if there is a Pac/Alanis Collab, she probibly is just doing the hooks or backing Pac as he raps, and, if it ever leaks, will probibly dissappoint peoples high expectations for this song.
imo, its an amaru remix for either RUST or more likely Greatest Hits.
