good thread - and some interesting opinions here!
on one hand i absolutely agree about the fact that a wrong chosen track
midset might bring a whole journey to an abrupt halt. if you're totally in the zone (as PL calls it) in the midst of a really good undergroundy set (may it be deep house, tech house or techno) and you're just dancing and lost in the music, you simply don't want to hear a track that once topped the charts.
but on the other hand, as a lover of classics (even if they're cheesy sometimes), i really like to get a few classics thrown in
at the end of the night. i don't even mind ultra nate's free - it's happy, cheerful and it takes away a bit of the seriousness of all the undergound clubbing and works as a send off track. i actually think this might be luci's idea about playing this one. but yes, as olly correctly stated, the best classsics are the ones that you've forgotten and then release old memories when they get aired again!
(and still, i very much preferred when luciano played chymera-arabesque at the end of his sets
that was a closer of sorts!)
