I am using a Verizon Thunderbolt that recently upgraded to ICS. Downloaded files using MP3 Music Download & MP3 Music Download Best. I have tried the stock player, Winamp & N7Player. N7Player worked for a bit. Then I accidently deleted a song. downloaded again and now won't play. Plus N7 keeps crashing. I have moved the file from where it was and put it in my Music folder, added it to que, added to playlists and still nothing. The player apps list it, I see it but when I go to play, it plays the next song. If I go to the file using Astro file manager I can play the song by tapping and then using either the stock app, Winamp or N7. Any suggestions please?
