Changi li style

Hi. First of all thanks for using the theme. In order to change the style, please create a child theme and override the base styles.

Right now I have made the music icon to appear before all list items in widgets under sidebar.

You can change that icon by writing

.widget_meta li:before, .widget_recent_entries li:before, .widget_recent_comments li:before, .widget_archive li:before, .widget_categories li:before {
 content: "\f054";
}

The above code in stylesheet of child theme will replace the music icon with a chevron icon. In the exact way you can override other css of theme.
