ITunes split my album after importing

Question

just got my new imac with latest version of itunes.
and turned on home sharing, merged both libraries from my macbook pro and this new imac.
and most albums has been split, and i drag to think to import the entire collection all over again.
so i thought i import a brand new album into my new imac to see if is still the same, and yes, itunes split it again.
any help is much appreciated.
thanks.

Answer 1

This is entirely a metadata issue. I have had the problem with various imports of music. Generally, to get a full album together that has been split, you can select all the tracks of that album, then alter the metadata - there are many ways to use the 'get info' metadata editor to bring all the tracks together for a particular selection.
As suggested above, checking the compilation box can work in many cases - I prefer that only for compilation albums because I use the iTunes keep media folder organized option.
Also, as mentioned above, setting an album artist - as different than what may be in the song artist for individual tracks - can work.
Also, if an album has more than one CD, then you can use the disc number, 1 of 2 then 2 of 2, and so on, to further refine how iTunes lists your music collection.
Another trick I have used is to set the album artist as 'Various' - if you do that, then you don't need the compilations box checked, but iTunes will create a new artist called various, and put the music so designated there.
Most of the things you can do that will help are in the 'get info' - info window, but sometimes it helps to use the 'get info' - sorting window.
Also, sometimes you find metadata that you want to delete in various fields as you work through the metadata of your collection.
Unfortunately, there is probably not much you can do with the entire library at once in this regard that keeps iTunes music folders organized nicely. But there is the unlikely possibility that, if you are viewing your entire library, say in list view, you may have selected a header that causes the albums to be split - set to view as list, highlight 'album' (as opposed to album by artist or artist/year) - then scroll though fixing any split albums as you go, using the method of selecting the album tracks, get info, and adjusting the metadata as you prefer for each album. It is a process, but it is also thoughrough.
There are some free scripts you may want to download that will do some helpful batch processing
I have made much use of  - hubi's iTunes scripts - the download page isn't English, but the script download is easy to find, just click the following link and scroll till you see
hubi's iTunes scripts
the read me instructions and script list are in English
hubi's scripts work for batch selections of tracks - so if you import an album and find the metadata screwed up somehow, you can select the whole set of screwed up tags at once (even across a series of albums), run the easy to use script, and watch it all be fixed automatically while you sit back and relax... I would advise running a script on a small test selection of tracks first - just to get used to and familiar with how it works and to see that does what you intend - I haven't had any problems with the ones I used.

there are other useful scripts out there, like Doug's Scripts

Anyway, I hope all that helps.
just for reference, here is a sampling of what some of hubi's scripts can do...
01-(un)capitalizes
01-(un)capitalizes
This script changes.... THIS TEXT into This Text... or this text
01-Delete spaces
Sometimes invisible blanks are behind an artist name or album name...this script deletes these blanks behind or infront of the strings
01-Delete x first-last chars. of Title
A Name like "01--Ray Of Light" will be changed to "Ray Of Light" and the01 will be entered in the tracks tracknumber id3 field =)
01-fix combined Artist-Title
Sometimes Tracknames look like:
"Madonna---Ray of Light" and in the artist field you see something like"Ripped by Me"... this script puts Madonna back to the right field... all youhave to do is to enter the right delimiter ("---" in this case)
01-switch Artist<->Title...
Switch ID3 field a with ID3 field b (not only Artist with Title any more =)!
01-z_filename ->Title
Sets the ID3 field Title to the track's filename)
01-z_trackNr-Filename->ID3
When a track's filename look like "01-Madonna-Ray of Light.mp3" andyou don't have the track's tracknumber stored in the ID3 Tag... this Scriptcan do this for your =)
