Yes, you read the headline correctly. There is no way to rephrase this post written by TMZ today:

The older brother who was killed and suspected in the Boston bombings was deep into hip hop, and it appears he belonged to a fan website that touted that genre of music.

Tamerlan Tsarnaev has an email associated with the website, "Real-hiphop.com."
The site provides information about hip hop artists and upcoming DVD releases.
What's interesting ... hip hop lyrics are notoriously violent and often degrading to women.  Tamerlan Tsarnaev has a boxing profile in which he says he doesn't take his shirt off much because he doesn't want women to get bad ideas, adding, "I'm very religious."  This statement is significantly more conservative than the hip hop genre. 

It is not clear how belonging to "Real-hiphop.com," a website which simply provides information about artists in the genre, can be connected to a bomber's deep seeded hatred for the men, women and children who suffered Monday (April 15) in Boston.

Oh, wait, it's those "notoriously violent and often degrading lyrics" that are obviously to blame for this tragic attack.
