Songs skipping ahead,

[user-removed]

My songs start at weird times mainly 40 or 50 seconds in and all songs do this they get to a certain point (like say a bass drop) and play another song to me it sounds like 2 songs playing at the same time but I cannot confirm that I've troubleshooted my device plenty of times I'm a tech geek and I troubleshoot almost daily now can a developer explain to me what broke in the coding for this application it feels corrupted.
