Syncing checked songs

You have changed the songs you have checked where? iTunes? Did you update the selected music to sync on the Music Device Profile tab and then sync?

Cheers,

When you open iTunes, and click on your device, you see a sidebar with Info, Music, Photos, Books, etc.

Select the Music option, and you will see a screen to the right that has a "Sync Music" option, one of which is sync selected songs, albums, artists, etc.

When you select that box, you then select the music you want sync'd.

Cheers,
