One side effect of the vagueness of the law and the creation of the loophole is the expansion of the concept at the hands of online music sharing websites. In 2009, the website Jango created a plan to accept promotion fees legally by disclosing that they are paid to play the songs. "For as little as $30, a band can buy 1,000 plays on the music-streaming service, slotted in between established artists. The artists themselves choose what other music they'd like to be played next to."
