I still feel their impact. Generally, when I come to like music it isn't just a phase and I'll just always like it. When it comes to punk rock, a lot of what is said resonated with me deeply as a teen, and frankly it still does to a fair degree. There's one odd exception. I don't really like Dream Theater anymore. I don't know why, but for some reason they died for me. Anything else I got into, I've stayed into. I have an album recommendation for you when you have the time. I only discovered this a few weeks back - perhaps you know it? If you haven't heard it, take the time to have a gander at some point.
I'll stay on topic now.
