Must have to

Hi!

I wonder why there are two models which sound similari the following sentence. Are there some different functions between these two words?

"If you want to know what Aerosmith albums, you must have to be a real fan?"

Thank you for your teaching.

Tom

I don't understand the sentence. A variation:

If you want to enjoy Aerosmith albums, you have to be a real fan.

If you want to know what Aerosmith albums mean, you have to be a real fan.

Leave out "must."
