If you're on linux (which it sounds like you are if you are using 'rename'), you can use find.
# find <folder> -type d

That will return every subdirectory of <folder> . You can use '.' for 'current directory. You can use the '-exec' flag to execute commands on each folder as it finds them:

# find . -type d -exec chmod 755 {} \;
This does a chmod for each folder to 755. {} is the result of the find, and you need to escape the ending semicolon, which tells find that "I'm done executing commands, move on to the next result".

However, in your case, you probably want to find all the files that end in .mp3 and execute a command on that file. Like so:

# find . -iname \*.mp3 -type f -exec rename "'" "-"* {} \;

My suggestion,however, would be to print out your command before you just blast it off:

# find . -iname \*.mp3 -type f -exec echo rename \"\'\" \"-\" {} \;

A lot of times I write this output to a file, and then execute the file with sh:

# find . -iname \*.mp3 -type f -exec echo rename \"\'\" \"-\" {} \; > file.sh
# sh file.sh

There's probably another 10 ways to come up with how to do this, but this is how I'd do it.
