The Verge: This was Sony Music’s contract with Spotify 

In section 4(a), Spotify agrees to pay a $25 million advance for the two years of the contract: $9 million the first year and $16 million the second, with a $17.5 million advance for the optional third year to Sony Music. The contract stipulates that the advance must be paid in installments every three months, but Spotify can recoup this money if it earns over that amount in the corresponding contract year.But what the contract doesn’t stipulate is what Sony Music can and will do with the advance money. Does it go into a pot to be divided between Sony Music’s artists, or does the label keep it to itself? According to a music industry source, labels routinely keep advances for themselves.
