Hey, its not always easy to read, it requires continuous practice and development
Anything I should do to become a better reader?
One thing you should do is develop different strategies, these can help you to decode meaning and aid comprehension
Any particular strategies you would recommend?
One strategy you can use is subvocalization, this is really useful when speed reading
That involves saying words in your head while reading so you can internally "hear" what the words sound like.
Yeah, its a totally natural process when reading, and it can help you access meanings and remember what you've read. 
Do you think classical music in the background aids or hinders reading comprehension?
It can be useful, but it might also distract from reading. It is up to each individual to see what works best. 
I'll have to try with music and without music to see which way I read better.
