Connections in Music Data

I am a huge music fan, listening to a pretty wide range of genres. While I work from home I will often have YouTube playing in the background. Sometimes something will jog my memory and I will remember a song I haven't heard in awhile, and with the power of the Internet I will research the group or the artist and see what connections I can find. 

I think this fascination comes from an early Rainbow CD I had, that in the linear notes, was a foldout chart showing all the people who played in Rainbow, Deep Purple, and other bands from that time. The particular visual I believe was created by Pete Frame, an early rock journalist who founded ZigZag magazine and created many Rock Family Trees. The particular visual is included in one of his Rock Family Tree books and are copyrighted. 

Fortunately, user BostboweL posted a spreadsheet on Reddit under the r/blacksabbath forum, showing a lot of the same information. Its a lot cleaner than the original one I remember, but it gets the point across, that there was a lot of cross pollination in the hard rock of the 70's and 80's.

What got me thinking about this? I was listening to a song I hadn't heard in awhile, did my usual research, and found these three songs that have a common connection. They are all from around the same ten year span (1994-2004). The music videos below are of those songs below, and at first glance they appear to be unrelated. With data exploration I found there was a connection.

Danielle Brisebois - Gimme Little Sign

New Radical - Someday We'll Know

Natasha Bedingfield - Unwritten

 

This is the kind of data exploration we do as part of Business Intelligence and Data Science. Taking seemingly unrelated content, and finding the commonality between them. In the real world we would want to use that information we have gleemed to make some decision or take some kind of action. Maybe from a marketing/sales perspective, we could use the connection to suggest to a buyer other products that they may interested in.

So what do they have in common? I'll let you figure it out. :)
