Is that right? Never knew why it sounds so unpleasant and, as Zanshin said, unintelligible, just know that it does. Funnily enough, the neighbouring Black Country accent sounds quite pleasant although equally as hard to understand.

I'm a Scouser and my home city's accent divides opinions. It can sound wonderful but also pretty horrible and be difficult to understand. Having left at 8 years old though and lived in several different parts of England (and the BVI for a couple of years) my accent is pretty hard to identify.
