Rockbox Rocks

I wanted to put a bunch of music on a Sansa Clip+ or Sport Clip and both seriously messed up the order of the tracks. First, ID3 v1 doesn't support more than 255 tracks, which wasn't enough. I used mutagen (https://bitbucket.org/lazka/mutagen) to make sure the tracks were numbered correctly via this script

TOTAL=`ls -1 | wc -l | sed -e "s/ //g"`
COUNT=1

for i in *
do
    mid3v2 -T "$COUNT/$TOTAL" "$i"
    mid3v2 --delete-v1 "$i"
    COUNT=$((COUNT+1))
done

The downside with mutagen is that it always converts to ID3 v2.4 that many players won't recognize. Nicely, with mp3tag (http://www.mp3tag.de/en/) one can choose the version desired, and there is an automated track numbering tool. Still no joy. As best as I can tell, the Sansa clips have a bug or two that make the whole effort futile. Enter Rockbox (http://www.rockbox.org/). I had no idea there was such a thing as free music player firmware. Cool! I downloaded the installer and the necessary Sansa firmware from http://forums.sandisk.com/t5/Sansa-Clip-Sansa-Clip/Sansa-Clip-Firmware-Update-01-02-16/td-p/150227, ran the installer, and it worked! So I did what I always do: donated to the mp3tag and Rockbox projects. The Clip Sport is not currently supported by Rockbox...
I learned far more about mp3 tagging than I ever wanted to, so thought I'd pass a little of the learning on.
