I was organizing my office and came across some CD's of MP3s I had put together back in the late 90's early 00's. I made an album folder in iTunes under compilations and dropped the songs in there. I then added them to iTunes under File - Add song to library. They had no information attached to them so I went through and added them. The problem is that now I have multiple albums instead of one album. Each artist gets their own album in the master listing which is really annoying.
After a bit of Google-fu I came across this: iLounge Forum post which explained what I needed to do. Select all of the items in question, right click, Get Info, on the Options tab selection "Part of a Compilation" Yes
