So you want to remove the "/music/artist1/album1/ogg-songs" folder but 
keep "/music/artist1/album2/flac-songs"?

If I got it right, you have something like this:

sm01@stt008:~/Desktop$ ls -la music/artist1/*/*
music/artist1/album1/ogg-songs:
total 0
drwxr-xr-x 2 sm01 sm01 104 may 18 22:31 .
drwxr-xr-x 3 sm01 sm01  80 may 18 22:29 ..
-rw-r--r-- 1 sm01 sm01   0 may 18 22:31 test2.ogg
-rw-r--r-- 1 sm01 sm01   0 may 18 22:31 test.ogg

music/artist1/album2/flac-songs:
total 0
drwxr-xr-x 2 sm01 sm01 112 may 18 22:32 .
drwxr-xr-x 3 sm01 sm01  80 may 18 22:29 ..
-rw-r--r-- 1 sm01 sm01   0 may 18 22:32 test2.flac
-rw-r--r-- 1 sm01 sm01   0 may 18 22:32 test.flac

To get/filter the ogg songs (or the ogg folder) you can:

sm01@stt008:~/Desktop$ ls -la music/artist1/*/ | grep ogg
drwxr-xr-x 2 sm01 sm01 104 may 18 22:31 ogg-songs

or:

sm01@stt008:~/Desktop$ ls -la music/artist1/*/* | grep .ogg
music/artist1/album1/ogg-songs:
-rw-r--r-- 1 sm01 sm01   0 may 18 22:31 test2.ogg
-rw-r--r-- 1 sm01 sm01   0 may 18 22:31 test.ogg

This is a simple approach. For a script, if you want to delete files/folders, 
use the "file" command instead, it's safer.
