If only Soundcloud/Mixcloud integrated it so you saw the current track while the mix played - likely avoided for copyright deniability?
In fact, as an uploader, you can still see it (I don't know why), but not as a listener. As an example, here's a screenshot of me viewing my own upload: https://imgur.com/a/REpxOgx
Editing tools still allow you to post accurate timestamps: https://i.imgur.com/gZabJUx.png
There's also a browser extension that modifies Mixcloud pages to display the tracklists again, but they're useless since no uploader has an incentive to go through the painful process of entering timestamps, and that process is now crowdsourced anyway thanks to 1001tracklists.
So a pretty narrow demographic for the feature though...
If you're only going to take one person's usage then, yeah, I guess it's pretty narrow. How about another example for from the same person. As a video editor I'm constantly having to find "hip/trendy/cool" music for video edits. These clients typically like music that I do not normally listen to, but I know it's something they would like when I hear it. I'll let it live in My Shazams until one day I need to find something. I've impressed more than one client with the ability to pull out a "fresh" song for them. Clients appreciate that sort of thing.
How about it? We've just added video editor looking for cool music to DJ. We could add tens such cases more, but all those combined are still narrow demographics.
Also, diabetes narrow? 30 million have it in the US, I'd say those are way more than DJs that need to recognize tunes, and have much more motive to use an app that helps them keep track of something that can have huge impact on their health...
I also use My Shazams as a potential mix list. If I have an item in My Shazams, it caught my attention for some reason. Just putting those tracks together into a set has worked out pretty well. It gets tricky if I'm using my phone as the streaming source. At that point, I usually just take a screen grab. If it's an individual track, I have artist/track name, and if it's a mix, I can use the playhead position to narrow down which track it was later.
