The service I'm working on is still in its infancy, but I'd love to hear what people think of the concept; it basically helps musicians and photographers expose their content to a wider audience, and on the flip side, allows you to sit back and listen to a playlist of music whilst enjoying a beautiful photo slide show. The playlists are tailored to a user's mood, and you're able to filter the music based on genre. The website's voliyo.com, and if anyone's interested in signing up to the beta as a photographer or musician, feel free to message me for an invite code!

So, here'd be my concern with that. I very rarely put on music and just "experience" it. Usually when I put on music it's in the background while I work on other things. I can't imagine myself ever wanting to look at a photo slideshow while listening to music.

Thanks for the feedback! You're not alone in sharing this view, so I'd definitely like to try and find a conceptual workaround for those who like to keep their music open in a background tab.

My exact concern w/ how Google is treating Waze. Songza was great for curated playlists. I might find a round about way to leveraging Nokia Music on my iPhone (I've got it on a WP8 lumia that I use for dev) ... it's not bad. Not the same, but better than other options.
