...I think it does not take an expert or necessarily a die-hard fan to realize that unheard stuff attracts more than any other "rare" but released stuff, especially in the internet days. There's always been a clear distinction between released and unreleased in any form. They used to label "previously unreleased" to b-sides in the 80s and 90s to boost single sales: Supernatural, Ain't no big deal, Let down your guard... how could be different now? What is the unheard factor when releasing the single edits of You Can Dance as an exclusive? Release Warning Signs and they see the fanbase is suddenly united in tastes!
