You know, I am really sick of all the poxy little gits who launch themselves on the internet, sing in funny accents, and then are lapped up by the public because they are 'quirky'.
Sandi Thom (debatably) launched herself on the internet, and went international with an interesting, fresh song that got a lot of airplay, and which I like very much. However, her next song was pretty boring, and she hasn't crossed my event horizon since. Having said that, I am glad she made it, because that one song was worth it; so the criticisms made here are not levelled at her.
Sandi Thom isn't really crap, though. Really crap are the Arctic Monkeys, who (so far as I can tell) are only famous for launching themselves on the internet. Their music is samey, and was never that interesting in the first place.
Even more crap are The Kooks, who, while they didn't launch themselves on the internet seem to have won international fame for singing boring songs in a cockney accent. As far as I am concerned singing in an accent hasn't made anyone cool since the Proclaimers, and they only pulled it off because they could actually perform a couple of decent songs reasonably well.
My pet peeve, among this group of accent-laden internet superstars, though, is Lily Allen. She can't sing, people! Her voice is even worse than Bob Dylan, Billy Corgan, and nails down a chalkboard put together. Her songs are repetitive and boring, and to me her accent sounds decidedly fake. And yet somehow she made it into the Triple J top 100 five friggin' times, despite being the worst kind of trashy pop.
These people might be marginally quirky if they weren't all the same, but they aren't interesting enough to be worthwhile.
