you hereby grant Spotify a non-exclusive, transferable, sublicensable, royalty-free, fully paid, irrevocable, worldwide license to reproduce, make available, perform and display, translate, modify, create derivative works from (such as transcripts of User Content), distribute, and otherwise use any such User Content through any medium

Why is this even legal anywhere ? How does one consent to something that is unknown at the time of signing?
