Music sure has changed since I was a youth. The way we find new music, the way we listen, and the way we share what we’re listening to has all changed; and the political and social climate of today’s culture is reflected in today’s music in a way that has changed massively since 20 years ago*. But I don’t look back and think, “now that was good music!”
Get something loud that can take a beating. Beyond that, punk amps should be able to handle a sound somewhere between classic rock and metal. The amp will live and die by how it produces overdrive, but you’ll need a more rounded sound that doesn’t have as much high end as well. If you buy something with multiple smaller speakers, you’ll be able to keep your high end definition without cranking the EQ to compensate.
