Why does my music randomly stop?

[AC Question]

Hello. I have problem with Honor 7 Lite (Huawei). I bought it about 1 month back and it worked completely well but few weeks later music started randomly stoping when I was listening to it. It's happening with every song and it's really annoying. It always stops about half of the song but it show the song is still playing while it does not. When I click on it again it plays from the point I clicked on it. Altought it happens with EVERY song I have. It doesn't work with headphones either. I don't know why it does that, but it really annoys me and I can't play any song on my phone without stopping this way.
Maybe some app would help?
Thank you for any advice.
