Billboard: Britney Spears' 'World' Angles for Top 5 of Hot 100, Thanks to Remix
Industry prognosticators suggest that all versions of "Till" (the original, the new "Femme" remix and its other assorted dance mixes) may sell around
210,000 or more by week's end on Sunday, May 1. That would secure its best sales frame yet, trumping the 158,000 it moved after its first full week on sale in March. Last week, the song shifted 122,000 downloads.
