Actually that is the most basic principle for a musician or a music major.
But, that's not bad to have problem like that.
My suggestion is :
- Try to listen song as much as you can, put your heart into the song, feel it, and "touch" the rhythm.. Maybe you'll still feel hard at the first time BUT as long as you do with your concentration, fun and focus, you will get it done for sure!
One more important mindset to all musician in the world.. "Musics are beautiful, its truly the piece of the Creator's art, I love it, and I let myself for them.."
Hope it helps..
