I love mashups when they do something really simple and really smart. Tim Bowman’s clear little mashup takes the technology behind Last.fm to recommend a whole load of videos for you to watch from You Tube. You simply type in an artist or a last.fm username and you get an instant video channel, rather than just listening to a a bunch of audio clips! It works pretty well, in the example (below) I put in 70’s UK art-punks Wire and got 70’s US art-punks Per Ubu! If you want to see what I’d recommend just type in nickwatt into the search box!
