Playlists you create have this icon 
next to them.

Edit a playlist
Select the playlist and do any of the following:
Add items: Click Edit Playlist, drag items to the playlist on the right, then click Done.
Change the order of songs: Drag the songs into the order you want. If you can’t drag a song, click the column heading above the numbers.
Remove an item: Select the item and press the Delete key (this does not remove the item from your library or storage device).
Quickly add an item to a playlist

You can also create a Smart Playlist that updates automatically based on rules you choose, or a Genius playlist that includes music in your library that’s similar to the selected song.
