My friend Aaron has compiled an Rdio playlist of every song ever played on MTV's Amp, a show from the mid-90s that featured electronic music. Lots of Underworld, Prodigy, Aphex Twin, and Orbital on here.
Some songs weren't available on Rdio, but there's more than 18 hours of music here.
Streaming music service Rdio (which I have been enjoying the hell out of for the past couple months1) is launching a streaming video service called Vdio.
The first thing you'll notice about Vdio is that it's designed to solve the "what to watch" problem. It's not just that we've got amazing content, but that the experience is now geared to get you from searching to watching faster. We're introducing the notion of Sets -- playlists for TV shows and movies -- so anyone can make and share lists of their favorites, making it easier than ever to discover new stuff. Or, you can just check out what your friends are watching in the moment and jump in. Beyond that, Vdio has the beautiful design and social features that people love about Rdio, with plenty more to come.
I haven't played with it too much, but it looks like it's not an all-you-can-eat service like Rdio...you buy/rent movies and TV shows just like iTunes, Amazon, etc.
 And that's actually a huge understatement. I ignored streaming music services like Rdio and Spotify when they came out, opting for the familiarity of iTunes, but Rdio has completely reignited my love of music over the past two months. Should write a whole post about this at some point. ↩
Put in a year and hear popular songs from that year with Radio Time Machine. If you have a Rdio account, you can hear full songs. See also YouTube Time Machine. (via @fchimero)
