not to blow smoke up my own chimney but i recommend checking out some of my sets: https://soundcloud.com/oxykon i mix mainly Drum & Bass, i'm no Andy C but i still have some good sets out, i've been mixing DnB for going on 5 years now and i still sometimes struggle with beat matching, like Mitch said, practice is the key. Some people find it hard to mix because it's so fast but i personally think it's way easier because of that reason, you gotta start somewhere man
