This has been happening a lot to me lately, where between tracks or at the end of an album this really loud and rather weird noise (that I can best describe as something you might hear Michael Bay's Transformers make) happens for a solid 5 seconds. It always scares the hell out of me. I emailed SPotify support but I figured I'd try and post here as well to see if anyone else was having this issue.
Solved! Go to Solution.
I have upgraded to Jelly bean now and uped to the latest Spotify version from Play. I have enabled the eq again and i havent hade the terrible noice yet. But now i got even worse problems, like spotify switsches song in the middle of a song (happend 10+ during a 35 minuts play time) but that will become a new bug report.
