I have tried most of the more enduring Android music apps, and Musicolet is among the best 10-15 of them, ever. But they don't all have good equalization options. "Bass boost" is catchy and popular, but being able to adjust things like track gain, album gain, pre-amp & post-amp levels, etc... makes ALL the difference on your average Android. Despite it's clunky UI, ArmAmp has been my favorite for about a decade and it has those things plus individually tuneable EQ bands. (Also anyone who ever used Deadbeef - which is what I used before - should be able to cope with ArmAmp's UI.)
