Well, it seems that I just misunderstand this word. There is a word with similar meaning in my language (means music or other art with many easily digestible elements, supposedly more appealing to casual people). It may be derogatory but is often used in ironic or neutral context, basically it depends on how much the speakers care whether their own musical tastes look advanced enough.
Here at Psynews, whenever people talk about my favoruite psy acts, such as U-recken, Digicult, Chromosome, Protoculture (older stuff), even Astral Projection, there always is at least one prerson calling them cheesy, as I understand, because of the "normal" melodies often reminiscent of regular trance or other "inferior" genres. Eventually I started using this definition myself when talkng about the kinds of psytrance I actually like the most.
I highly respect Tristan's technical skills and I can enjoy a track or two by him, but without proper melodies it quickly becomes boring to me. I really love all these metallic noices and trippy/squelchy/bubbling grooves but I prefer them to be contrasted by something more melodious. I guess I'm not a real psychedelia lover but frankly I couldn't care less.
Yet another fine track, imo it has good balance between harsh sounds and euphoric melodies
Btw, all these tracks posted by Blubber are absolutely amazing. But as I understand most of them are made in the early to mid 00's. Shame that I didn't knew much about psytrance at that time, I think if I had been listening to it then I woud have enjoyed much bigger part of the scene than I do now.
