You can sue them. If is not specified that must be in a row you CAN sue, or at least you can report them with the competent organization. It's in normal language, not legal language. People using spotify are not lawyers, are normal people. If the thing says "30 minutes free" it do must mean that, no "ooohhh you mean, 30 minutes, like, in row??" bullshit.
Fuck Spotify. Also, I can't hear the music that I want in their free plan, because I choose some song and the platform plays whatever they want. Again, fuck them.




Ahhh I remember when pozole was invented in the early 80's down the street in some block in the bronx
