I don't listen to as much punk as I used to, so a lot of them are kind of older, but that's the style I generally like too, I don't generally like singers that aren't "singing"
for Millencolin? I haven't listened to them much in a long time, I'm just looking through some of my old music from when I listened to this style more regularly
so I don't really know their newer ones, but Pennybridge Pioneers was good... 10 years ago
one thing you might want to try is getting ahold of some punk compilation albums, there are quite a few of them that come out regularly, then you can just skim through a bunch of different bands quickly
