Hey this has come up before, but check out the black-and-white examples of wise marketing: Enslaved, a band I don't listen to, is streaming their new album here. Trivium, a band I hate, is streaming their new album here. One record would've slipped by unbeknownst to HooM! and the other would've been ignored. One record slays, and the other is an encouraging improvement by a young, developing group.
Making entire albums available is especially pertinent to heavy music. With some variation, this is how Metal people get into bands: You jump into your friend's car (or Scott Burns' pick-up) and dude presses play on some shit you haven't heard. You shred, you shrug, or you sneer. But you're poised to like it cause your wallet is no lighter and your bud is trustworthy (he got you into The Crown, The Ocean, and uh Scatterbrain). So streaming entire albums stirs up the same feelings, as the band themselves screech up alongside you in their Camaro let you give their new record a fair listen. Bravo Enslaved, Trivium. Listen up major labels!
