Question

use of "to" here.
I love  listen to music. 
If I say " I love listen  music". What is wrong with it. What is the meaning of "to" here.

Answer

Two things to fix.

1) Pay attention to the verb form after a verb. "I love listening" and "I love to listen" are correct, but "I love listen" doesn't exist.

2) It's easiest to remember "listen TO ____". That's all you need to know. If you really want to analyse the grammar, then look up "transitive verbs" and "intransitive verbs".

Answer

It should be "I love to listen to music' or 'I love listening to music' or 'Music is something that I love listening to'

to usually goes with the word listen....except in commands like 'You need to listen' or 'Listen carefully'

Answer

The sentence is incorrect. You could write it as:
"I love to listen to music" or
"I love listening to music"
