Tens of thousands of people have been killed in drug-related violence in Mexico over the past seven years. Most of the violence is attributed to fighting between rival drug gangs for control of territory and drug shipment routes.
The free edition of Pandora can stream music over the Web at a bitrate of 128 Kpbs or 57.6MB per hour. This could mount up to a significant usage each month. For example, if you listed to Pandora for one hour each weekday while commuting, you would use at least 1.1GB over a month containing 20 workdays.
Initially, users with free accounts could listen to 40 hours of music a month, and could pay $.99 per month for unlimited streaming. In September 2011, Pandora removed the 40 hour listening limit. This 40 hour limit on free listening was re-introduced in March 2013 for mobile devices.
