bash-3.2$
To create a playlist, we just reverse the format and redirect the output to a file (with extension pla) and then copy the generated file to Sansa's PLAYLIST folder. Just to remember, the path of each file is relative to MUSIC folder.

addr="$(echo $1 | sed 's/ /+/g')"
values="$(curl -s $converter$addr | cut -d\" -f13,15 |sed 's/[^0-9\.\,\-]//g; s/,$//')"
lat1=$(echo $values | cut -d, -f1)
long1=$(echo $values | cut -d, -f2)
