You don’t own songs on spotify, you merely license the temporary right to listen to them. Therefore the proper comparison is not album sales, it’s radio plays.
Now I don’t know the average rate for radio licensing, but I’m willing to bet big money that it’s absolutely nowhere near $200 for 20 people listening.
Maybe radio is not as cheap as spotify, maybe not, but famously spotify is not profitable so the labels are still to blame regardless.
