Love
1 - The unique hip-hop sound. Just like when I hear a reggae bass line, I'm reminded of my early years living near Notting Hill, when I hear a hip-hop beat, or a flow, it just reacts with me in a way that no other style of music does, even if it's a song I love. I guess that's just the soul of hip-hop.
2 - The fact that it's been around long enough to build up a sense of history and growth. Jay-Z is someone I couldn't stand in his younger days, and his early stuff still doesn't move me, but the way he's matured, and started to become a bit more thoughtful, makes him so much more appealing to me, and is a great microcosm of what's happened in a lot of the genre. I hold out hope that even the people I can't stand now, like Souljah Boy or 50 Cent might grow into artists I can respect.
3 - International flavours. In the UK, Hip-hop took a long time to find a voice that worked for it. It was very insular, seeing other genres like dancehall and drum & bass as rivals, but in the last 10 years, it's incorporated all of those things to make a genuinely British sound that is getting the artistic and sales recognition that we never dreamed of decades back. This is not just here either, there are hip-hop acts in every country, and many of them have moved beyong imitating the US styles, and created something that truly represents their culture, and is being accepted in the US (look at Estelle, Sway, K'Naan, etc.).
Hates
1 - Nigga. I'll simply never accept it as anything other than a hurtful, self-hating term. I hope we move past it.
2 - The mass market. As hip-hop became the global musical force, it necessarily lost some of it's integrity. Politics, positivity and respect are harder to market than stereotypes, tits, ass, drugs and crime. That said, I feel we're reaching a point where the positive is starting to find new ways to come through.
3 - Lack of progress. There are some places hip-hop needs to move forward on, which have been so stubborn - sexism, homophobia, and probably the largest issue - how to define black masculinity in a healthy way.
