Hard to give an opinion without a chosen object
But i took 2 of them and gave them a listen.

Pawel Bednarek - Distored Pleasure (Parc Ferme Pres. Paranoise's Distorted Elements Remix) *Preview*

I hear some nice hard trance elements.
But they really need a louder kick with more punch to get a hard feel.
Now it sounds more like psychadelic Goa ,only needs a goa kick and rolling bassline to become psy goa.
Has a nice old skool feel to it though.

Big Bang - Blue (Parc Ferme Progressive Remix) *Free Track*

Very nice song ,easy flow ,feels like lounge dance.
I don't understand the language ,so could be the language
But sounds like the vocals are a bit off key at some places
But the voices of the singers are good for a Cher effect on your AutoTune Plugin if you have that.
With that effect on it you take the notes to the right note
And with that type of voice i think you can even get a nice cher effect
So thats what i would try if i were you.
