OnSong is incredibly flexible when it comes to importing and exporting your content. To use your content in other apps, use the Open feature in the Share Menu. You would use the same steps as found in the Email screen such as selecting your format, etc. However, when you tap on the Open In button at the top, simply select Gmail. That will open the composition screen in Gmail with the file attached.
How can I use the Gmail app to send emails instead of the built-in Mail app?
