I use the folder, sub folder structure to organise the tracks into albums. Every album is a folder containing all the pertaining tracks and multiple albums are grouped into a larger folder that specifies the genre. The album art, chosen and downloaded from the net, is inserted into each album folder. I Prefer to keep the Library in the folder mode and listen to all the tracks from one album. If you follow this pattern there should be no hitch unless you have activated the Shuffle as pointed by Andre in the previous post.
