I'll never forget when I first discovered Napster. I was in high school and had heard about it from a friend. As an avid music fan, I was delighted to suddenly find myself with access to a seemingly limitless trove of songs, some of which were previously available only on $40 CD-R bootlegs in the back of record shops where they also sold paraphernalia strictly designed for smoking tobacco and only tobacco.

I never abandoned purchasing music all together, but the MP3 struck me as a far more convenient format than the compact disc, and Napster gave me quick and easy access to a world of MP3's. When Radiohead's "Kid A" showed up on Napster weeks before the CD was available in stores, what was I supposed to do? Ignore it?

A music discovery app for iOS that went live recently shows just what's possible when digital music services open up their libraries and functionality via powerful APIs. Twist Radio takes the music recommendation engine from Last.fm and uses it to help users explore music from SoundCloud.

The result is an app that lets users discover more obscure, independent and often homemade music, rather than a catalogue of music that's only been formally released by record labels. That's because SoundCloud hosts mostly user-generated music, including covers, mashups and original compositions. Some more established artists and labels have even embraced Soundcloud and uploaded commercially released albums to the service. It's essentially the YouTube of audio.

Clear Channel, the largest radio station owner in the United States, has teamed up with music intelligence platform The Echo Nest to build an Internet radio service similar to Pandora and Last.fm.

Clear Channel's iHeartRadio service uses The Echo Nest's massive dataset of 30 million songs and 5 billion related data points to let users create radio stations based on their musical tastes. It has been dubbed a potential "Pandora killer" by Billboard and indeed its functionality could hardly be more similar to Pandora's. Users can create stations based on a particular artist or song, vote tracks up or down and skip a limited number of songs per station.

Lightbox, a beautifully designed photo sharing and camera replacement app originally launched into beta at this year's SXSW. Between then and today's public launch, the app has been overhauled, and has added support for Honeycomb tablets. But what's most interesting about Lightbox is its business model: "Android First."

What that means is that developers behind Lightbox, lead by founders Thai Tran and Nilesh Patel, are building Android applications first, before building the iOS counterparts. And that hasn't always been an easy task, they say.

NPR music podcast All Songs Considered just released a show about breaking up with your favorite bands. It got me thinking about favorite web apps or services that I've broken up with. So in the tradition of Internet era music, I'm going to directly rip NPR's idea and breakup categories.

In this post I tearfully discuss past relationships with MySpace, Last.fm and Soup.io. I finish with a love story that has a happier ending: Flickr. I'd love to hear your own tales of web app woe in the comments.

There's a fine line between what is considered a knowledge database and an invasion of privacy, and that line is likely to be determined by marketing. This week we wrote an article about Please Rob Me - a service that identifies Foursquare and Gowalla check-ins on Twitter and lets others know that a person is not home. While location-based services are often touted for their social and recommendation-based benefits, the realization that they can be used negatively have many questioning the responsibility of those groups that collect the data.

While the rest of the world was caught up with Google Buzz, Apple was quietly granted a patent for a virtual reality App Store. The store patent encompasses details such as seasonal and time-based lighting, color schemes and a basic storefront representation. A few bloggers have already criticized the patent as a relic from SecondLife past, the store may have more use when we consider it in the context of the XBox Live marketplace.

Looking at a regular graph of traffic data from Digg and Facebook, it would be easy to assume that Digg is lagging far behind Facebook's staggering growth. However, Compete just produced a very different graph that compares traffic at Digg and Facebook since their respective launches, and according to this data, Digg is actually doing better than Facebook. Facebook is obviously older than Digg, so while it has more traffic now, Digg's growth since its inception has actually been faster than Facebook's.

Index Ventures today announced the closing of a €350 million early-stage fund, Index Ventures V. Early stage? Wow! And early stage + Europe = Double Wow! How does Index Ventures raise such big funds for early-stage ventures when most investors are still trying to figure out if Treasury Bonds are too risky? In short, it is because it has already invested in some of Europe's biggest successes, most notably Skype, MySQL, and Last.fm. When you get those kinds of exits ($4.1 billion for Skype, $1 billion for MySQL, and $280 million for Last.fm), investors want to give you more money to try again.

People's Music Store is a newly launched DIY online music store. It was created by the founder of MP3 reseller Bleep.com, Ged Day. People's Music Store styles itself as "the first music store entirely powered by music fans." Basically the service allows you to set up your own custom-designed record store, with music chosen from a catalogue of indie record labels (so far no major record label music). The idea is that you earn points, equivalent to 10% of the price of the single, EP or album that you sell. These points can only be used to buy other music items on the People's Music Store site.
