Backticks are obsolete, and problematic when nested. Modern Bourne shells, BusyBox included, undestand $()-notation.

Code:

for i in $(seq $n); do mpl mp3 $i;done

If $n is very large, then while-loop may be needed to avoid exceeding command line length limitation.

Code:

i=1
while test $i -le 100000; do
	mpl mp3 $i
	i=$(( $i + 1 ))
done
