My music library on my laptop is in WAV format. The ID3 tags work well on the laptop. But when I transfer to my Droid, the files seem to lose the "artist" information... which makes them all appear as "Unknown Artist" in my Droid. I have some mp3s on my laptop. I transferred them to the Droid with no problem. All the ID3 info appears to be available. So I tried converting the WAV files to OGG, but it was the same story after transferring to the Droid. Does anyone else have any WAV files they could try this with?
