I thought I'd add some of my own music to the /music directory of the sd card. All good so far. Transferred a shed-load of files over via Windows Explorer. Then I got round to deleting the hald dozen sample files put there by HTC as the music wasn't to my taste and was taking up room. This seemed to go well too, but the artists, and track titles still appear on the HTC Music app, the only difference being that they now state that they are an unplayable format (HTC-speak for 'they're not there' I guess). Is there some other file I have to edit when getting rid of all traces of this music? Will I have the same problem if I delete my own selections?
