Spotify's volume is noticeably lower than other players'

[jny1]

It's been for more than a month already. Equalizer is turned off completely. I've tried many different players and streaming services like Rdio, Apple Music, Vox, Tuneshell and what I noticed is that they sound a lot louder than Spotify. I have to turn the volume up to 100% in order to achieve the volume of 85% of other music players. Is it just me or somebody else faced this problem? Wanna know if it can be fixed somehow.

P.S: Have this issue on my Macbook as well, but on mac it's loud enough for me, so wanna fix this problem at least in mobile version.

Thank you!
