People usually convert their music files from MP3 to the AAC audio format ’cause it gives better quality at lower bit rate, it means almost same quality at lower file size. But the android users get disappointed when they see a bug in Android which doesn’t recognize the tags of the AAC audio files. This totally disorganizes the organized music library.
There is a fix for this problem, just download the MediaFix Application from the Google Play (Android Market) and scan all the media files in your phone storage which application does on ow and your Music Library will be as good as new. So that’s the solution for now, Hope Android fixes this bug in Upcoming Androids.
