All my music on my Lumia 820 SD card now won't play and comes up with error code 80070003. It had been playing fine. Anyone else got this problem or suggestions?

My 920 is giving me the same error. Did you ever figure it out? Thanks!

I did three things that seemed to cure it. Reduced my sd card to a 16gb size, turned off all xbox settings and finally in wmp I set the conversion rate for files higher than the default. Not sure if it was one or all that made the difference but all the music files now play great.

Hey! So I was really irritated over the same error code, the only thing that I found to solve it on my Windows Phone 8 is to plug your phone into your computer "open to view files" using windows explorer, and cut the ORIGINAL download from your computer, and paste it to the music section in your phone. Don't rename it, don't create a new folder, don't pass go, don't collect $200. Your phone should work all of that out for you. Finally, my songs are playing. If you have bought the music and you don't want to run the risk of having it only in your phone, you can get a free copy form mp3skull.com
That's where I get all of my music, buying it is a waste of time because most of the time I end up losing it..
Hope this helped!

I have a Nokia 822 with expandable micro SD card. Specs say 64 gb is possible, I use a 32 gb. After weeks of frustrations with music I think I have something working now. I've chatted with Nokia's site, no luck - didn't get anyone who had a real answer.

Everytime I put an mp3 or wma file on the phone from my own PC collection, the file would 50% of time time be unreadable with error 80070002 or 80070003 or other errors. The card would become corrupt and I would reformat it on my PC. I tried FAT32, exFAT both with the same result. I would only use the Windows Phone desktop app for Win7 to move the files and would get the errors. If I stored the music on the phone's internal memory it seemed to work better (at least the corruption would stop) but again 50% of the files where not playable. I even tried an old 8gb card, same problem so I went back to my 32 gb class 10.

I tried to transcode all my music to .wma as this format seemed more friendly, I was wrong same problems. So I did the hard this and hard reset the phone and re-formatted the SD card and started fresh. Some music transferred with no errors, but then the playable problem persisted again with mp3 or wma.

I noticed that WP8 supports AAC files, so I transcoded all my files to AAC (actually .m4a which is just another file extension but is AAC format inside). I use foobar2000 freeware to do the work.

Then I transferred the music using just windows explorer and low and behold the music is there are readable. You even get a windows pop-up saying that the device doesn't support .m4a files but I transferred them anyway and it's working perfectly. Hard to beleive mp3 and wma implementation on WP8 is so terrible, even my BlackBerry handeled this with ease. Love everything about the phone, I just don't like to have to transcode music to listen to it.

Similar problems here. What I am going to suggest is defiantly not going to solve all of the music (sync) problems but do eject your phone when removing from computer. This is not the main issue but I feel in some cases it could defiantly be exacerbating the problem.
