These days people mainly buy singles, and need to be pushed for te album. Platforms as Spotify work well for "preview usage", but youtube or ITunes in this case can have the same effect beforehand.
It will be a good way to gain extra exposure for the album, since everybody will be able to stream it, just a select amount of people will find links to download it. But most of the GP who will buy it or atleast consider it, will not even download it illegally just stream it
