I used this command to recursively gather all mp3 files that were previously imported into their own directories (sorted by band name) in Songbird.

No problem with word splitting. That should works on many Unix likes.
This command copies all filenames in the current dir and subdirs that end in .mp3 regardless of case (also matches .MP3 .mP3 and .Mp3)
It copies all the files to the "mp3" folder in your home directory.
If you want to see the files that are beeing copied, replace "cp {}" with "cp -v {}"
If you can do better, submit your command here.
