iTunes import or album problem...

After importing a music CD sometimes I find one or two of the songs from the same album is
in a different folder by itself. The song from the album is usually titled Song Whatever..."Featuring
name of different artist".
How do I get all the songs from the same album in the same folder?
Drag & Drop doesn't work.
Thank You,
Doug

Use the Album Artist tag

For instance, I have a album by Mark Ronson with various guest artists

I keep the Artist as Mark Ronson feat Lilly Allen but select the whole Album and put Mark Ronson in the Album Artists field, voila, all the tracks are moved into the Mark Ronson folder

dont see why you couldnt just make a smart playlist with a criterion being 'artist contains (whoever)'
