I have been trying to import a bunch of songs from Guitar Hero III into iTunes and have them appear as single album. While it worked great for Rock Band, I couldn’t get it to work for Guitar Hero III. After messing around with every logical control available with Get Info, I finally found a post which explained it. Changing the Album Artist field to Various Artists did the trick and now I only have one Guitar Hero three album in the album view instead of one for every song!
