ABOUT MEDIABASE MUSIC CHARTS: YELLOW HIGHLIGHT DENOTES CHART DEBUT. BULLET INDICATES INCREASE IN AIRPLAY OVER
PREVIOUS WEEK. Mediabase electronically monitors more than 1,700 radio stations in the top 150 U.S. metro markets,
24-hours-a-day, seven-days-a-week. Those radio stations are broken out into specific radio "panels," and included in the
most appropriate "format" above. Songs moving downward for a pre-specified number of weeks are removed from the charts.
All charts are based on radio spins, with the exception of Country which is points based. Mediabase is the leading radio
monitoring service with broadcast companies in the US. Mediabase also serves virtually every significant recording
company, and associated entertainment industries. Copyright, Mediabase 2010. All rights reserved.
