multiple files opened in awk

Hi ,
i' d like to use an awk script to automate the ripping of cds : here's how it works :

- i first create a file named songs.txt containing the name of the songs
- the scripts extracts the tracks of a cd with cdparanoia
- the scripts saves the contents of the dir with ls (ls > list.txt)
- the scripts rename each filename contained in list.txt by its equivalent in songs.txt

i don't know how to do the last step , because it implies to have multiple files opened at the same time ...

do you know how to do it?

MPD-DYNAMIC(1p) 					User Contributed Perl Documentation					   MPD-DYNAMIC(1p)

NAME
mpd-dynamic - a dynamic playlist for mpd VERSION
version 1.120610 DESCRIPTION
This program implements a dynamic playlist for MPD, build on top of the Audio::MPD perl module. MPD (music player daemon) is a cool music player, but it lacks a dynamic playlist. A dynamic playlist is a playlist that will change automatically over time. In particular, it will remove already played songs (keeping at most a given number of songs) and add new songs to the playlist so it never fall short of songs. Note that since mpd is a daemon needing no gui to work, "mpd-dynamic" is also a daemon. That is, it will fork and do all its work from the background. This way, you can fire "mpd" and "mpd-dynamic" and forget completely about your music (especially since "mpd-dynamic" is a low-resource program): it will just be there! :-) USAGE
mpd-dynamic [options] OPTIONS
General behaviour You can customize the usage of mpd-dynamic with the following options: -o[ld] <old> Number of old tracks to keep in the backlog. Defaults to 10. -n[ew] <new> Number of new tracks to keep in the to-be-played playlist. Defaults to 10. -s[leep] <sleep> Time spent sleeping (in seconds) before checking if playlist should be updated. Default to 5 seconds. -d[ebug] Run mpd-dynamic in debug mode. In particular, the program will not daemonize itself. Default to false. -e[ncoding] <encoding> Print debug messages with this encoding. Since mpd-dynamic is meant to be a silent daemon, this option will not be used outside of debug mode. Default to "utf-8". --version --usage --help --man Print the usual program information Note however that those flags are optional: since "mpd-dynamic" comes with some sane defaults, you can fire "mpd-dynamic" as is. Ratings You can also take advantage of ratings if you want. With those options, songs need to have at least a given rating (or no rating yet) to be inserted: this way, you will only listen to your favorite songs! Ratings can be created / updated with "mpd-rate". Note that if you supply a non-existant rating db-file, the rating mechanism will be ignored. The following options control the rating mechanism: -r[atings] <ratings> The path of a db file with the ratings per song. The keys are the song path (relative to MPD root), and the value is an integer (the rating). Default to "~/.mpd/ratings.db". -m[in[imum]] <min> The minimum rating for a song to be inserted in the playlist. Default to 4. AUTHOR
