I mostly have on music. In addition to airplay, I have a large and extensive collection of probably about 600 vinyl albums and a similar amount of CDs, all are stored Alpha by artist and then release date within the artist. I have a 400 CD jukebox player and am going through it alphabetically. First off, just by nature of the technology pretty much everything in there is at least 10 years old and I have forgotten owning some or having others in other formats, so expect to hear things that I don't as well as hearing things I don't expect. Plus the shifts of genres between artists can be huge! Shortly before the Super Bowl it was like a like a mini half time, I had the Gipsy Kings (so all Spanish), Green Day, and Brandi Carlile in the Highwomen -- I'm almost out of I now but I haven't been sewing so much.
Sometime I do listen to audio books, but I have to be at certain points in the projects to where the sewing is pretty much automatic and doesn't require a lot of thought or really captivated by a story that I want more.
There are also times when I just want to hear human voices in the background and I will also put on TV/movies. Usually I want good stories that I already know/don't have to watch, like from my personal collection the Back to the Future movie series. For TV I want people talking nicely (no screaming or fighting) and doing what I find interesting things, so home improvement shows or real estate shows or cooking shows are likely.
