Just some random musings. Qawalli (which is admittedly a good tune) isn't the kind of thing you'd expect in the top ten. I'm guessing with the scoring system being what it is a track like this placed high in say, two peoples top tens, is going to rank higher than for example Sticky's Golly Gosh, even in twenty people voted for it as their 25th favourite tune. At the end of the day Benny didn't have that many polls to work with, and is presumably not a mathematician by trade- the first twenty have been largely predictable and there's nowt wrong with that.
In regards to 2000 garage being ineligible because it's a relic of the previous decade. I would counter that it's top ten chasing characteristics are the very reason why these records should be considered as authentically noughties. There couldn't have been more than five 2-step tunes in the UK charts in '98/99. I doubt many producers were intentionally making tracks with that goal in mind. Then as soon as you're into the new millennium people are jumping over themselves trying to get a single signed to a major, Dreem Teem land a high profile slot on national radio (admittedly by filling their schedule with 90% commercial R&B and often inane banter), So Solid are in the tabloids for the wrong reasons, etc. And it was that creeping commercialisation that gave birth to the bassline & MCing dominated backlash, hence DJ Zinc, Shut Up & Dance, Pulse X etc.
Ice Rink as an instrumental wouldn't have featured high on many peoples lists but with all the different versions to choose from it's a fair inclusion.
I predict that Jon E Cash or Todd Edwards won't feature in the Top 10, how do you choose a single track when they've made so many good ones.
