// Run our code later in case this loads prior to any required plugins.
add_action('widgets_init', 'widget_lastfm_init');

?>

and then the insert into your template is this:

<?php lastfm_tracks("username"); ?>

It should be noted that the above PHP script adds WP Widget functionality as well, so most of that wouldn’t be required for TXP site, and so the plugin in theory would be lighter. x

I can appreciate that people would like some reward for their effort, but I’m not really in the position of being able to pay for plugins!
I should imagine that quite a few people would like to see a professional last.fm plugin for TXP! WordPress has loads. Hopefully someone can code one up soon. x

So, what exactly are the requested features? Just display x-num most recent songs played for y-user ?

Basically YES! But it would be awesome to have some control over what data is shown etc. Most people don’t show the songs they have listened to (but some do) they show the last 5 albums regardless of what songs they have listened from each, be it be one song or the whole album.

As a basic concept, wrapping be in this form:

<txp:abc_lastfm></txp:abc_lastfm>

and then have some additional tags such as:

<txp:abc_lastfm_recentsongs limit=“10” link=“true” />
<txp:abc_lastfm_recentartists />
<txp:abc_lastfm_recentalbums />

I’d like a last.fm plugin to do everything I want without asking too. It should be able to read my mind – judge what music I like, serve up plenty of compatible options for me to choose from – if I can be bothered to click- , show my latest things I’ve listened to, wetc, and of course completey free. Cheers! Oh, and please tell me how it fits in with txp. I use lst fm independently but would love to know how it all fits in with textpattern. Cheers!!! Hic.

What’s the point in saying something like that! You drunk? :S
