Here’s a cute hack which uses LastFM to find songs similar to the one currently playing in MPD and add them to your playlist: more-like-this.rb.
To use it just run
more-like-this while MPD is playing and 10 similar songs will be appended to the playlist. Give it a numeric argument to add a different number.
You’ll need a few Ruby gems for this to work:
gem install librmpd scrobbler
So, yes, I’ve finally switched from Amarok to MPD. Sadly after the greatness of Amarok 1.4, each new release takes giant backward steps in usability – at least for my use cases :(. GMPC is OK as a client, and I’m really liking the programability.
