It's the first time Last.fm is bringing music videos to its site, which beganlast month.
"We want to offer a video library that rivals our unparalleled music catalog, as we work towards Last.fm becoming the only place you need to go to for all music-related content," co-founder Martin Stiksel said in a statement, "and this deal marks the first step towards that goal."
