Here's a great way to start 2016, Win an award for "Best Domestic Bathroom Installer 2015".
My brother David entered the Geberit Awards, Geberit being a large multinational manufacturer of bathroom products and out of all the entries from all of the UK, he won. We're very proud :-)
That prompted us to finish editing a timelapse video of the winning bathroom. Rather than a silent movie sound I went searching for suitable music to accompany the movie and found the track "Pamgaea" by Kevin McCleod. Best of all, the licence to use this sound track was 'Royalty Free' as well as being free of cost on condition it was clearly attributed to the author. That's very much like the software code I've written and shared, although Kevin is a master of his craft, whereas I'm just an amateur coding for fun.
As well as free when attributed, the music can also be licensed for a fee when an attribution is not possible or wanted. Example: Background music when you're on hold. In my mind I always thought licensing that type of music was expensive, turns out to be a lot less than I expected.
