Not that I want to encourage you to steal music (I’d hate coughing up for Mr TimeWarnerUniversalMegastores’s dole money as much as giving empty praise to its products) but a few forthcoming albums have been “digitally previewed” in one way or another including:
Sunna (click through for an explanation of how the band that was set to write the Spiderman 2 theme fell into obscurity)
*= full album has leaked/is legally available to stream
Any that I missed?
Incidentally, The Hype Machine have added this nifty twitter chart to their service, for those of us who like to Microscrobble.
*EDIT* Add Fuck Buttons to that list
