Shuffle Glitch

[doodoo_peehole]

Hi!

I have noticed two very strange glitches to do with shuffle on both the Windows and iOS version of spotify:

1. Re-shuffling a list by pressing the shuffle button twice will retain the next song and not consider it when shuffling.
2. Shuffling will shuffle about 30 songs only, and shuffling only songs begining with letters A-C.

Maybe it's bacause I have too many songs? (I have 554 songs - I just chacked).

Any help is appreciated.
