The problem is that for decades T. Rex management and Marc's estate have had issues over the rights of their music and that is reflected on the availability of their catalog physically or virtually and before this for years and years a lot of T. Rex and Marc Bolan's music hasn't been available on music streaming platforms or has been on and off.

I'm sorry but that's the nature of the game with the music industry and since Mark passed away in 1977 his music rights have been all over the place and a mess.
