Brummie - I grew up there so love it.

South Wales - My maternal family are from Aberdare and the accent is a real joy to hear.

Irish - especially the west.

Sing-songy accents like west country, Lancashire and Yorkshire.

Also London - on my paternal side the families roots are in the east end and easter side of the city since the year dot, and despite being in west London for a generation or two they've not lost their cockney brogue or love of life, and are wonderful family to have.
