You can customise which columns are shown in a folder by right-clicking on any column header, then on 'More' and putting a tick next to each header that you want to appear.
If you've got subfolders within 'Music' that aren't being recognised as containing music files, try the following:
Go to 'This PC'.
Right-click on the 'Music' folder.
Select 'Properties'.
Click the 'Customize' tab.
Check that 'Optimize this folder for' is showing 'Music'.
Then put a tick next to 'Also apply this template to all subfolders'.
Click 'OK'.
The above procedure can, of course, be used with any other folder too, such as your 'CD Collection' one.
