I am a new with iREALb so maybe I am not using the correct settings so I hope someone can help.

I love the Beatles and have downloaded the Beatles song collection. When I play the songs they don't sound
anything like the original songs.

For example, I wanted to learn the song "Let It Be". When I listened to it there was no resemblance to the original song.

I have found this to be the case with many songs, not just Beatles but other artists as well.

Seems like all of the songs play with a limited number of 'styles' but not how the song was originally composed and recorded.

What am I doing wrong?
