There's always been this debate about whether MCs complement or undermine the music. There are good arguments on both sides, but I suppose there's room to please everyone, not like you can't avoid MCs if you want. I always really enjoyed a good MC who knew how to flow nicely, nowadays more often I listen to mixes without MCs but not exclusively. I strongly agree with the point about MCs being lazy. In jungle/dnb it always seemed like a near closed shop in terms of the DJs and MCs at the top of the game. The MCs were comfortable knowing their name was big and they'd be in demand, so they spend their entire careers rinsing out the same lyrics.
I was listening to Eksman the other day and although he had some different lyrics to what I'd heard him saying before (I haven't listened to him in years btw), it was all a load of 'I'm a gangsta and I've got a gun" bullsh8t.
