Basically, cause I need to do this anyway, here's some crunching. All these are stats for the chart "Billboard Hot 100" and are straight off Billboard.com (which gets its data from Neilsen Soundscan, according to SS' homepage). There's one link for each song that'll at least get you the chart peak position & weeks. There are (gasp) 50-some pages of results, tho, mostly because of the Puff Daddy remix hitting about ten different charts for twenty or so weeks apiece.
I count six top 10 singles, tho "Spirits" came painfully close at #11. And "EBYT" holding a spot on the "Adult Contemporary Recurrent" chart over the span of a decade ought to count for something...
Roxanne: Peak position: 32 (weeks on chart: 13)
Message: Peak position: 74 (weeks on chart: 7)
De Do Do Do: Peak position: 10 (weeks on chart: 21)
Don't Stand: Peak position: 10 (weeks on chart: 18.)
ELTSDIM: Peak position: 3 (weeks: 19)
Spirits (the single): Peak: 11 (weeks: 13)
Secret Journey: Peak: 46 (weeks: 3)
EBYT: Peak: 1 (weeks: 22)
KOP: Peak: 3 (weeks: 16)
Sync 2: Peak: 16 (weeks: 13)
Wrapped: Peak: 8 (weeks: 7)
DSSCTM '86: Peak: 46 (weeks: 9)
Roxanne '97 - Puff Daddy Remix: Peak: 59 (weeks: 13)
Other items of note:
* EBYT went to #23 on the "Hot Singles Recurrent" chart in 1997/1998 when the Puff Daddy song "Missing You", which sampled it heavily, came out. Weeks on chart: 20.
Also, it charted on a few other categories, most notably "Hot Adult Contemporary Recurrent", which it hit in 1997, and stuck around. Peak: 5; weeks: Who knows? Its most recent listing, for this week (April 9, 2009) lists the number of weeks as "247". We could probably parse this out if anybody really wants to know, but for now, just realize it hit that chart after the Puff Daddy thing and has pretty well held a spot on it for a decade.
* "Roxanne '97" also charted in categories like "Hot R&B/Hip Hop Singles" and "R&B/Hip Hop Airplay."
* A tune called "When The World Is Runnin Down (You Can t Go Wrong)" by "Different Gear Vs. The Police" went to #7 on the Hot Dance Club Play chart back in 2000. Weeks: 8 (Note: I have a copy of this and can post it if anybody wants it)

No worries, hon - great if all this is helpful, if not, feel free to rewrite. I'll get around to locating dates for the chart peaks for the Wiki shortly, most likely.
