How should I practice?

You also learn subtleties of expression which you might miss and you feel like part of the music.

If you are curious , you can learn about the music behind the songs which you can use for other songs too!

If you are playing lead guitar, once you have learnt the notes ,you need to turn down the volume of the record so you can feel the subtleties of your guitar sound.

And most importantly HAVE FUN !
