I'm trying to re-organize my music files. I copied them from my iPod before it died, so they have funky names, like DGEDH.mp3. I tried using a Windows utility to rename them from their ID3 tags, but it didn't work very well--it created a bunch of folders (one for each album in theory, but more like 7 or 8 in reality) and renamed the files with non-English characters. Most of the files are MP3s, but there's at least one or two other file types as well.

I'd like to copy them to a new folder and try a Ubuntu utility to rename and re-organize them. In Windows, this would be straightforward--I'd use the Search function (with no file name specified) to list all of the files in the main folder and its subfolders, then drag and drop them to the new folder. What's the easiest way to accomplish the same thing in Ubuntu? The GUI search doesn't seem to accept wildcard characters, and I don't remember all of the file types I have, so it's not as simple as searching for "mp3".

Many thanks!
