tracks() click to toggle source

Query the website, parse the list of tracks and return a hash: { :previous => [ <track> ],

:current => <track>,

A track is also a hash: { :artist => “…”,

:album => "...",
:title => "...",
:remaining => "...", <-- remaining time
:time => "..." <-- time for previous tracks

}
