If you're like me and want to keep all your music rated, and you use xmms2, you might like this command.

I takes 10 random songs from your xmms2 library that don't have any rating, and adds them to your current playlist. You can then rate them in another xmms2 client that supports rating (I like kuechenstation).

I'm pretty sure there's a better way to do the grep ... | sed ... part, probably with awk, but I don't know awk, so I'd welcome any suggestions.

function jumpTo { xmms2 jump `xmms2 list | grep -i '$1' | head -n 1 | tail -n 1 | sed -re 's@.+\[(.+)/.+\] (.+)@\1@'`; }

Usage:

Declare this function in your Shell, then use it like this:

> jumpTo foo

The script will search for the 'foo' pattern in your current xmms2 playlist (artist or songname), and play the first occurence of it !
