the real ego, I'm afraid I have to agree with tman. Those tunes you mentioned are too commercial, and some a tad cheesy. Out of the bunch I'd only give marks to Underworld (preferably for Dark & Long), and Stardust MSBWY (but it would have to be a remix).
Everyone can name stuff fresh off the back of one of those Ibiza compilation or Euphoria CDs. But you might as well be bowing down to Top 30 Hits. Their utter pants, and get played the most just when you're sick and tired of hearing them.
In the Dance (and not so much Electronic) industry there are a lot of artists in it for the money, and tend to churn out a similar sound. Exibit ATB, southside spinners, etc. They were all around in the dayz of MOS. They may be a tad out of date, but it was around that time, I just had it with that kind of stuff. Like I remember being at some rave a couple of years back, and it was the first time I heard Fragma - "Toca Me" (on White label, ATT). The crowd went mad, but then what did Fragma do?, they went and used their winning formula again, with Toca's Miracle (a rip off of Coco - "I need a miracle", last released on Positiva also). It was a joke, and instantly put them in the commercial scene, to be forgotten by the clubbing generation. A bad move, and a lot of those kind of money driven artists are found on the tracklisting to those all too common compilation CDs that hit you at the door of every music shop.
Having said all that, people still like them, coz if their ending up in the charts, somebody must be buying them. But those people who think their being exposed to dance music, are unfortunatly being held back from the good stuff and drawn in to this neon world of cheesy tunes. This point has been proven by the sheer amount of compilation CDs that are released every month, just because the demand is there.
But go in to any good record shop (not high street Virgin/Golden discs etc), but one that specializes in dance, and has staff that know their stuff, and you will soon realise what you've been missing. I will admit, I was one of you before I started Djing 3 years ago. Through that I was soon exposed to a completely different side of things, and it was all good
