So for the last few weeks i had been watching something i downloaded which was a show counting down the 100 biggest selling 90's dance tracks in the UK. Don't know 100-95 as the person didn't record that but we have #94-1 with units sold. Take this with a grain of salt, i think it's pretty close but i would guess it doesn't include streams or downloads, ARIA positions in brackets

Additional Note: I forgot to edit that the #10 peaked at #84 on the ARIA chart. I'd never heard #63 and have checked the reports of the year of it's release (1995) and discogs and can find nothing to say it was even released here.

#63 is actually called Never Gonna Let You Go, and though the original is from 1995, it was a UK hit in 1997 via a remix.

(I noticed a few errors in your ARIA peaks: Strong Enough peaked at #11 not #2, Bamboogie peaked at #29 not #28, It's My Life peaked at #43 not #42, Get Ready For This peaked at #2 not #3, this version of Baker Street peaked at #100 not #1, Up & Down peaked at #55 not #53, Re-Rewind peaked at #62, King Of My Castle peaked at #26, One & One peaked at #56 not #52, Missing peaked at #2 not #1, and It's Like That peaked at #1 not #11.)

My bad with the peaks. i hadn't originally intended to include them. Some typos were a result of my annoying keyboard but i accept them anyway.
