What Tom's suggesting means your album will be a "various artists" compilation and should do the trick to keep everything together.

Another way, if you don't want "various artists" but you want it listed as a particular artist, is to set compilation = NO and to set "Album Artist" (this is the ID3 TPE2 tag, aka the "band" tag) for every track to be "Benni Benassi"

Then you will have the album sort under "Benni Benassi" even though individual songs may be from any number of different artists.

Don't hate iTunes for this simple issue. What you're describing here is basic tagging and the result should be the same regardless of whether you're using iTunes or iPod or something else. These settings are required to keep an album together if you have different artist names, otherwise there's no logical way for software to know that the different tracks actually belong to the same album, versus belonging to different albums with the same name.

The empeg didn't use tags to manage/organize/display your tracks, so it didn't matter what the tags were at all so long as you had the music organized properly in folders on your had drive. That's a very basic and inflexible way to deal with music. As far as handling music sorting and grouping, iTunes generally works very well (as of version 7). Newer versions have grown into bloated pigs with some poor UI choices, but that's not relevant here.

To be "complete" you should also set the iTunes tags for GAPLESS and DO NOT SHUFFLE for all the tracks. That should allow them to play without a gap and will prevent a shuffle mode from picking those tracks when played back in iTunes and iDevices.
