I have 170 GB of music, approximately 45,000 songs, on a legit sanDisk 200Gb UHS 1 card. Popped it in my Luima 950. Launched Groove... Groove shows toast message that it's adding the songs. About 10 a second. Ok, so this is going to take awhile but at least it seems to be working. Walk away, come back, total song count on toast message didn't change from when the screen turned off. Now it starts chugging away again, 10 songs a second. Ok, so either the message is inaccurate or this thing is really dumb and will only index while I'm sitting here looking at it. I don't have time to watch it index 45,000 songs so for the next couple days I just try and always have the app open. Somehow it gets to around 4,000 sings or so and then it just stops indexing. Some of my music is indexed and plays but most of it is not in Groove yet. Now what? How do I get Groove to finish building it's library. I'm open to any superior app suggestions also. I use Plex for streaming from my desktop but it's sync also seems overwhelmed with this large of a music collection. Anyone else had any luck with a large music collection on a SD card in a phone? Obviously I'm limited to Windows phone apps. HELP!
