batch convert to MP3

I've got a car MP3 player and immediately found out all my music is in various formats and it's a pain to copy something over to the player with the correct format.
Searching the net didn't show something reasonable for mass/batch/bulk converting files to mp3, at least not something that would really make the job easier. So I thought it's time for some bash again.
Here I have a script that given a list of sources which can be directories and files and a destination will go over known music files in sources and copy them to the destination with their relative paths preserved *AND* converted to MP3.
Conversion is performed by playing the file through mplayer which feeds pcm audio data to the lame mp3 encoder stdin. So a wide range of input formats are supported even video files where the first audio stream is processed.

./ <src1> ... <srcN> <dst>

For example if you have:
$ find
and run:
./ file1.flac dir1 dir2 dir4/dir5 <somedir>
you will end up with:
$ cd <somedir>
$ find

Script may need some small modifications depending lame or mplayer locations, lame/mplayer settings, additional file extensions might be necessary, stuff like that, but generally I think its ready to use.

Download it from here and let me know how it works for you. And before I forget again, file is licensed under GPLv3.
