Most music you are into tends to have great lyrics, from your own perspective of course. But I must agree that there are always certain artists who still manage to hit the tone a few bars over the rest.
Some of my favourites include (not surprisingly, these bands would propably be the same ones as on some sort of 'Akbar's list of the best bands ever'):
In English
Moneybrother
Monster (same singer and songwriter as the above band, but a whole different experience. More 'fuck you, I won't do what you tell me!' than 'You broke my heart, please come back', if you get the general idea)
Bob Dylan
Bruce Springsteen
In Flames (woot? Metal? Yes, fuck off.)
Broder Daniel (You think you're emo? Well... are you, punk? Seriously though, give this a try if you're thinking of putting together a dark and melancholic band. There's really no need for that, you see.)
In Swedish
Håkan Hellström (supposedly steals a lot from Mr. Dylan, but I couldn't care less. Bloody awesome lyrics in any case.)
Kent (duh!)
EBBA GRÖN
Thåström (from the above, an old swedish punk band)
