thiswoodeno Create and name your playlist with all 500 songs then choose that playlist, you will see six options above the play button choose the sixt one on the right that looks like a box with an arrow pointing upwards, select simple text, and then just enter email address of person or persons you want to send it to, the subject column is automatically filled with the playlists name.
TIP
In settings if you choose to have your songs numbered, when you print your list you can refference songs with clients by song number it works really well.
Great feature!
