Hi :)
I did the best I could. Here are some remarks regarding the translation.

And thank you for your hard work!
Salim.


=======================
text0.lng
Overall: playlist = liste de lecture and playlists = listes de lecture
if it's too long, you can still use playlist/playlists, or simply liste / listes. Everybody will understand.

Overall: I used tag for tag. There's a french correct word "balise" but it's not really used, people prefer.

line 148 : Rewind Setting ? I don't understand what it is.
line 157 : REMOVED , does it mean deleted? then it's EFFACÉS. If the files stay on the memory device but are just removed from the sight of the player, rather use IGNORÉS (ignored, that is bypassed).
line 160 : Blocking inc. no idea what that is
line 161 : Blocking off no idea what that is
line 162 : Player, Office : what's meant here?
line 173 : no idea how to translate samplerate, however, bitrate is "débit"
line 184 : I guess, should keep (empty) ?
line 186 : Information Wave, no idea how to translate it


=======================
text1.lng
line 2 : don't know what you mean by (while holding Reverse)
line 3 : idem with (with the forward hold)


=======================
text3.lng
line 1 : how can someone like an annex? :/ I changed it to "Programme"


=======================
text5.lng
line 1 : I think, annex means just the indexation of the music files on the phone into the musical library. I translated it this way.

line 31 : I added my name there, Salim Ramadan. Feel free to remove it if you wish to place it somewhere else.
