 4. Under the "<strong>Value Data</strong>" field add the attributes, "System.Music.Genre" and "System.Comment" anywhere you like depending how you would like the metadata to show in the tool tip. The "<strong>Value Data</strong>" filed consists of deifferent attributes that appear in the tooltip. For example "System.Media.Duration" is the Duration of the media. These attributes are separted by ";" (semicolon). I would recommend adding the Genre and Comment attributes after "System.Media.Duration".
