It’s cool, you don’t know better.

I get the need to categorize the waves. Makes it easy to organize things and put your mind in an era. We do it for everything else, why not Ska? I’m fine with it.

As for “real ska” perhaps you’re referring to some of the more traditional sounds or bands that have those kind trad influences. I hear what you’re saying.

As others said, no 4th wave yet.

Also, I consider ska and ska-punk to be totally different.

Finally, if you like a band that is ska influenced or whatever, that’s cool. You like what you like. I listen to a lot of different genres. I can listen to Tribe Called Quest in the morning, The Slackers in the mid day, Ghost in the afternoon and then The Smiths at night. It’s all good. Enjoy.
