maybe it is a good idea to hide the services that the user doesn't use.

now it is only 3 services. but if you add tidal/deeze/(i don't know what else is there)/... the list could get long and annoying to find the one service that you use.

if they are hidden and only show the services you actually have, then users don't have to search (unless they have ALL the services)

OR

orden then according to your music services priority, that way your preferred service would be on top.

Thank you, aerozol l! Yep, I started working on implementation, thank you very much for your help!

Great work kubrimskii! I think you can consider this UI aspect solved, for now (I'm sure there will be things to tweak later - for instance, if it turns out that these take a while to export, you may want a processing/loading screen).

The gsoc mentors are more dev-focused and will have more feedback for you once you get started on the code - it might be a good idea to start talking to the project mentor about your implementation ideas. And you can always ping me when you have more UI questions

aerozol thank you very much! Will look forward for it

(sorry for left-aligned text, will fix it xd)

UltimateRiff oh, that's a great point. I was thinking actually, mb to add other external services to export to (for example youtube), but will ask in IRC first. 
Thanks for suggestion !!

I feel like for the pop up (second image) should probably have the services in a grid, that way there's plenty of room for many more services to export to, but apart from that, looks great to me~

Full disclosure: I don't use Spotify and have not used the export function!
But this looks like an excellent improvement functionality-wise, and everything matches existing LB styles. The only thing I can nitpick (and I am good at nitpicking!!) is that popup titles are left-aligned.

There's not much UI complexity to work with here (which is good for GSoC) so I'll nudge some of the devs/gsoc mentors to feedback on the implementation and GSoC project aspects.
