Hi Cask and thanks for your support! I'm glad you took the time to send some ideas through - I'll post on each one if that's ok.
1) Unfortunately I am unable to add the artwork or track names to the lock screen as Microsoft have locked off that functionality going from Windows Phone 8.0 to Windows Phone 8.1 RT apps - which is a shame because I needed to make the app using the 8.1 framework so that playback of other file types were possible..
Until Microsoft restore that functionality, all I can suggest is to hit the lock screen button to bring the lock screen up and then hit volume up/down once (it won't change the volume on only one press) and then a bar will come from the top telling you what track it is.
Not ideal obviously but there's nothing more I can do on that one I'm sorry!
2) I have also thought about having some basic track tag editing functionality, along with the ability to delete files - I might do that for a future update. I'm just concerned if something goes wrong with the tags editing with the app I'd be ruining someone else's library and that concerns me!
3) Yeah the library idea is great and something I've been thinking of the best way to do.
Teh Jukebox isn't a library based player yet (just a file/folder one) but I could extend it with library functionality soon - just need to think about the best way to do so without slowing the app down too much!
I'll let you know about updates as I do them. I'm posting them in the thread I've made here:

Thanks again Cask!
