iPhone 4s, Local files crash after 5sec

[Muskeldon]

Hey guys,

i´m using an iPhone 4s and since a couple of days(last update), spotify really starts to annoying me.

Anytime when i play a local file on my iPhone, it plays 5secs oder less of the track - than spotify crashes complete.

Sometimes i have to restart the iPhone to play some music. I´m using iOS 8.2. I removed spotify from my iPhone and re-installed it, but it`s the same bug again -.-

Is there anything i can do about it? 80% of my files are local, so i cant hear 80% of my music. Thats not acceptable!
