Partly, yes.

Basically, no matter how much you "dislike" a type of music, if you are a producer and an artist, you will always learn something new from it.

And learning from other music rather than just one type will allow you to learn other techniques and skills, different rythms, different sounds, thus increasing your knowledge and skill bass allowing you to have more weapons in your arsenal when making your music of choice.

Or you can listen to one very narrow type of music and learn nothing more than how to sound just the same as someone else. In which case why not just buy their records and save yourself the time?
