Googles tiem because I haven't the foggiest how you're doing all that embedding.
M J Hibbett / The Validators / Artists Against Success (the man, his band, their label with various other cool, mostly hobbyist artists on). Songs about the largely upbeat but occasionally pretty dark realities of middle-UK life with a leicester twang. Infectious, clever, and unstoppable. Apparently it's like Billy Bragg with more instruments. Erm.
You want something a little harder than that along the same lines, then, quite literally you want The Twang themselves. They come from a couple miles away from where I work. Technically it's the black country, but it's not really that close or well connected with where Ozzy et al came from.
Spray - started out with AAS, splintering (or being a contributing part of, never quite sure) late 90s John Peel Show/UK chart "terrorists" the Cuban Boys (also still going, also worth a look & a laugh). More of an electro-goth group but with quite a sense of snarky humour. Very enjoyable and the female lead can really belt it out. On the Ninthwave label which has all sorts of slightly strange, electro/new romantic-ish artists of (to my mind) varying quality. Very much worth a look.
Even if all you get from it is I am Gothic, their cover of the Raccoons theme, and "Everything's better with muppets", but to rely on those would be to miss their other, slightly darker depths.
Anything, anything on a Damaged Goods sampler. The best thing is they're very cheap and varied. Designed to garner more sales for the bands in question and by 'eck it's effective.
Dubmood, 505, and various other chiptune warriors who aren't doing the same-old NES based schtick (not to belittle Anamanaguchi and the like, but their marketplace is kinda crowded). They make that YM2192 sing like an angel, and then add some actual instruments on top to make it even better. You'll believe that a whole album can get by without needing a single vocal or a tune that easily fits into an existing genre. (Oh, and if you can get hold of a bit of Mad Max as a sideline...). Just steer gently around all the endlessly slightly-changed cracktro and keygen themes, as you'll go crazy trying to figure which is which.
If you haven't run across Florence and the Machine, La Roux, Electric Six, The King or Richard Cheese yet, well, now's the time. And if you're not down with Rammstein or Tenacious D... GTFO.
(seriously, I may even go as far as to say don't bother with the albums straight away - get to an E6, RS or TD gig, and if you don't like it, don't bother with the discs... and give up on rock in general)
Final, slightly cheesier suggestion: If all you know of Bon Jovi, Stereophonics or The Offspring is their most recent stuff, do yourself a favour and go back into the late ('phonics) or mid 90s (Offspring), or early 80s thru early 90s (BJ). There's a fair amount of sameyness, but the parts that stand out truly do rock.
EDIT: Uber Evil: YES - how the hell did I forget Ash? A band who simply refuse to become crap? Throw on a bit of Kung Fu, Girl from Mars, Burn Baby Burn, etc whilst you're at it.
Also, "A". Defunct but producing of 4 pretty solid pop-punk albums, with only a slight tinge of sellout on the third... but it's still good.
Warning: If I put on my phone's music player later, there may be more additions.
