Your song will be sent to all blogs feeding into hypemachine (if you buy the extra), regardless of the genre. If you want genre specific promotion , check the 20$ extra.
Campaign will be sent out through a professional promo system, with send report, where you can see the number of contact reached. Unlike mail blast sent by email (low opening rate), our submissions are never tagged as spam. Opening rate is about 50%, the more you send the better is.
It is not guaranteed that you will get any review, nor that you get any soundcloud activity (unless you get reviewed ), but you'll be sure they listen to your track.
