As a whole, I’d label this stuff generically under the tab of “hard dance” honestly, though it’s tough to put such a broad moniker on anything like that. It’s like just calling all forms of house music, house.
It’s not hardstyle though, I can tell you that much.
I’m tired and drunk and don’t want to give each one a full listen right now, but I’d say they are more on the hardcore/hard-trance side of things just from the look through.
Here’s me looking them up individually on trackitdown.net I prefer using that site when looking for specific harder genre stuff, as it’s much better at labeling genre’s than beatport or even Juno I’ve found. Not perfect, but we can’t have everything.
Partystylerz - We are the Partystylerz - Hard Dance - Euro
Basshunter - Dota - Hard Dance
Corona - Rhythm of the Night (Eric Mullder Remix) (As this track is unreleased, wasn’t able to find the exact remix. But it looks like a hard dance remix of a house chib)
Cascada - Because The Night (Hitmen Remix) - Hardcore
Tune Up - Ravers Fantasy - Euro Trance
I listen to a lot of this stuff on my own, mostly Hardstyle and Hardcore honestly though. The big thing that you just get used to listening is the difference in speed, how they are set up, the drums… it just becomes natural after awhile. I have a buddy who likes to spin hard dance stuff, and it’s a tough thing. Because sometimes you have the hardcore or hardstyle tracks, but then you have a lot of hard-trance and whatnot as well.
Really, it’s just about finding the sound you want. If you have a pile of tracks that you absolutely love, figure out how to make them work for ya
And finding a good site that labels genre’s well is key, because a lot of the “popular” sites aren’t particularly good when it comes to the “harder” sounds.
But to me, it looks like you’re looking for Hard Dance, Hard Trance, and maybe a bit of the lighter Hardcore.
I’m no guru. I’m a guy outside Boston who loves this kind of music. You’d be very, very surprised at the size of the hardcore scene we have up here in New England (with ties to NYC as well, as much as I don’t like to admit it!).
But hope that helps
