What is the "La Haine" remix? Is that the person who made it? Know any alternate names or have anything extra to say about what it is? I've always been in touch with the 2Pac remix scene and I've never heard about that before.
And, to answer the last question, the place to look for stuff beyond spotify or youtube is either soulseek, google, or torrent sites. I have found tons of lossless rare albums on Soulseek. It is user share based so when you search, you only get results from people that are active online at the time. Meaning, if you can't find something right now, someone might log on in 10 mins, an hour or three weeks from now that have it. I thought music sharing was dead. Then someone told me about Soulseek. I didn't know things like this still existed. Do not underestimate how much you need Soulseek in your life. Not that you would find the remixes you asked about there, but generally speaking, you find TONS of stuff like that. For example, I've found tons of other 2Pac internet remixes on there. I searched for "2pac promo flac" and this is what I got (screenshot):

Look at the scroll bar.
Oh, and also. The 2Pac discord. And
www.bomb1st.com. And while on the subject, bomb1st's youtube has been booming lately. The Pac scene still thrives in case you didn't know! Still got buying groups, still got VIP sections, there's still tons of unheard songs out there from both pre-DR and DR era. Despite the some 300 new song and alternate version leaks we've had since the "old days". The tip of the iceberg was only the tip of the iceberg. There are exciting things ahead of us actually.
