Hi - sorry for the late response and thanks for the replies. The music library was originated on my laptop, the tracks were ripped there and the meta data then sourced. The tracks were then copied down to my mobile. The laptop library is the master and there is no need for Poweramp to get any of the meta data. Looking at one of the tracks that is coming up with unknown artist and album, going into Info/Tags, all the meta data is there ( artist, album, track etc ). All these similar tracks are coming up under unknown artist, the album doesn't appear in the album list.
Doing a Full Rescan, is this updating Poweramps own library or will this change the tag data for the tracks?
Thanks Greg
