iPhone music purchase problems

I downloaded (purchased) an album and a few singles to my iPhone 3GS from the iTunes store yesterday. Usually, iPhone purchases showed up in the "Purchased on ....(my)...iPhone" and they would automatically be added to my computer's iTunes music library. This time, when I connected my iPhone none of the songs appear in any of the "purchased" selections and only the singles downloaded to my library. The album had a digital booklet--which did get added--but the songs from the album did not load into iTunes. They are on my phone and I can play them through the iPod app.

How can i get this album into my iTunes? I don't see any selection to do this & I use my laptop through my home stereo pretty exclusively.

Thanks-
