Create a highly trafficked music streaming site, monetize it by injecting an Ebay marketplace, tax sales and split revenue with artists.
How do you make both content owners and consumers happy? Create a highly trafficked music site that gives consumers free music. Inject an E-bay like marketplace into that site allowing individual sellers to place targeted ads to an engaged audience. Tax that marketplace and split the revenue between Musicx.fm and the content owners. Everyone wins. Think Grooveshark monetized by E-bay.
