On the street I can hear music which has no low sound

from smartphone speaker

There is something at the bottom

but music which has no low sound has played

Right?

150Hz is abandoned  Where you are, 200Hz?

This speaker is too tiny to playback, no sense

Right?

Too much doing head-banging,

your neck had been something wrong

Right!?

I hadn't played the guitar for a long time

Fingertops of left hand has got soft now

Right?

Too much doing stage dive and mosh pit,

your back had been something wrong

Right!?

Until monday morning,

Looking back things happened at the Saturday night
