haha i don't actually send the email, they won't respond to randoms, i pay someone who they will actually respond to for sending in all my requests. i used to get one price request in every 5 weeks or so. there really isn't any predicting the prices, it depends on retrieval difficulty. about 35 percent of requests will get denied [see: Futuresex/Lovesounds , No Strings Attached

] because transfer was not authorised by the artist estate.
i know they do discounts for bulk transfers. for example if you just wanted 2 beats from BOMT it would be 1500, but the full album 3000. (You probably won't ever see this one . Don't know who tf would pay for these) Oops had a similar price structure, i was able to get 6 tracks for 2000. ITZ a bit cheaper, only 1500 for the full album and 200 per song ... But because of 'muh 5.1' nobody wants to help me pay this off, i refuse to contribute more than 500 myself.
then you have never gone and unbreakable which were only 750 apiece. i think most albums after 2004 would probably run you a similar price. But you can't fucking buy anything these days, due to corona the label ceased non-essential transfers since 18 March 2020. i was supposed to get unbreakable last year on 29 March . fuck corona i hate it so much still waiting all this time god damn it
Don't bother asking me about buying stems . You have to pay for one of their professionals to align and bounce it, so prohibitively expensive i would never try it
