1: Yea, it's a bit of a gap in there, but are you sure it's one of the worst problems to ask a fix for?
2: Go to the artist list, locate the album you wish to play, press the play button.
3: It's a limitation of the M6's hardware. What it cannot do, it cannot do. Only some software optimizations took it to 20FPS as well.
4: True, true...

5: Yes, it shouldn't however in a removable disk drive functionality, how on earth could the software detect you've put any music files on? Or deleted any? Felixperro, what checksum on the playlist? The M6 just would wanna decide if it has to be updated as the current is probably already old, there is nothing to compare it with. Unless reindexing. My guess is that manual playlist updating was taken out cuz of techsupports and returns that it doesn't read files from the less experienced...
6: Just check the lock or don't use it :D (it always just bothered me really when I used it)
7: Yea, true, but to say everything as well, I'm quite sure that the stuttering MP3 songs aren't fully right. If you re-encode the songs with a high quality encoder, they don't stutter.
8: Well, if you've only seen that bug once, then I believe it would be better if Meizu would spend their time on fixing other bugs instead.

9: Yea, I guess many people need that. On the other hand you should take a look at some posts here, someone had an idea to put all the song parts into one and showing the current song with a timed LRC subtitle file.
10: Nope it hasn't been.
11: If it's connected to the PC, you can use the PC to listen to songs, no?
12: Well... previous-next buttons

And don't forget you can hold your hand over the pad under the top and above the bottom button, that scrolls quite fast too.
13: Well, the SL's screen is just the way it's like I guess
Hope this contains some useful things
P.S.: felixperro, Rockbox would be a too big project! Noone wants to do it. Also, Meizu deliberately made the decision to not give a manual update function.
