File/Folder View problem / ?

I got a new computer with intel i7 chip and windows 7.
I had all of my music/photos/files backed up on a 2TB external harddrive.
I copied all of the files from the backup to the new computer harddrive.

Here's where it gets strange.

I have over 6000 songs that were kept in one folder each with the band name and track title.
On the new computer under my music every song (mp3 file) is in a folder for each specific album and another for each specific band which creates a lot of folders to dig through.
How can I get all of the songs to display as before (all of the songs in one folder and not folders within folders?
Thank you,
