#5. Never, ever, ever ask them to post your music right away!
The biggest mistake I’ve seen in all of my time promoting and trying to get features on blogs is trying to get them to post it! Never ask them directly to feature your music because you are getting a buzz, or that your music is dope, or that you are shareworthy. Blogs HATE this. They will despise you. This is actually a good way to get blackballed from the entire hip-hop community! Your message will be disregarded within a second. Come at them correct, and be polite. Get yourself featured by helping them make their lives easier.
