Mediabase is a radio airplay monitoring service (much like Billboard). It currently monitors about 120 country
radio stations. A list of those stations can be found
HERE.
NOTE: Mediabase updates their charts daily. The chart runs for Shania's singles here will be longer than
those on Billboard due to this. The runs in my archive start when the single debuts in the top 100 of the country singles
chart. And the runs end when the single either goes recurrent or starts to fall out. My chart archives consist
of the morning updates reported daily by Mediabase.
