The library is where you find and organize the songs you've imported into iTunes.
Click the Browse button to display a list of all your songs, organized by album and artist.
To sort the list, click the column heading. (For example, click Song to sort by song title.)
To reverse the sort order, click the triangle in the selected column's heading.
To rearrange the columns, drag the headings into the order you want. To resize a column, drag the borders between the column headers.
To display the musical genre of an album when you're browsing, choose Preferences from the iTunes application menu. Then click Show Genre When Browsing in the General pane.
