You have to label the album Top 100 of 2005 & 2006 BUT you also HAVE to label the arist as Various (or your choice just as long as its the same for every track on the album).
EDIT: Funny how its top 100 but you say theres 200 albums
okay I have the same problem but the albums I want to combine are only on my device and not on my computer do I have to sync my device to the computer?
