When online and mobile music services build their own content databases out of the labels' catalogs, they would have incentives to use the same numbers to identify each song, for the reasons laid out below. Music services already apply their own unique identifiers to songs in their catalogs, so the use of numbers is not the issue - they just need to be the same numbers. This database would have to be free, readily available and totally transparent, visible to music fans and industry people alike, because the barrier to entry for startups to use the system would have to be zero. Open source software making use of the data set, available on the same website, might encourage services to use the numbers."
