Do Rastafarians believe in Jesus as the Way to God? Do Rastafarians believe that Jesus is the way to God in the same way that Christians believe? I find that their singing speaks a lot about God and spiritual matters.
First of all, I think it's necessary to point out that Christianity is not defined by being a "lot about God and other spiritual matters". Most world religions could include this. You could just as easily be Muslim and sing a lot about a god and spiritual matters.

Even more specifically than that, a group may have a set of beliefs that draw on many common themes from Christianity without being Christian. Such is the case with the Rastafari Movement. It is a philosophy and loosely organized way of life that includes some common themes and often reuses terms and phrases found in Christianity, but at it's core is a completely separate set of beliefs.

To directly answer your question, no Rastafarians do not believe that Jesus is the way to God in the same way that the majority of Christians (of any major tradition) do. In fact they believe the Christian scriptures have been corrupted. Being a loosely organized set of beliefs it is important to note that you might run into a few people who do believe in Jesus and claim to be Rastafarian. However the normative Rastafari beliefs are quite different.

They do not hold the same beliefs about sin, the reasons for our separation from God or the only solution to that problem. They are usually willing to credit Jesus with being a good moral teacher and admire his rebel tendencies, but they completely miss the main point of who he was: God in the flesh and the only incarnate Messiah.

That last bit is important, because they typically do believe in a "christ" or "messiah", but they believe he had another name, took a body at another time, etc. See Haile Selassie, Emperor of Ethiopia, to whom Rastafarians attribute many of the things found in Christian scriptures rather than to Jesus Christ.

Confusingly, you might even hear "trinity" nomenclature being used by Rastafarians, but be aware that they mean something completely different by this than Christians:


  Rastafari doctrines concerning the Trinity include stressing the significance of the name "Haile Selassie," meaning power of the Trinity, might of the Trinity, powerful trinity in Ge'ez or also Haile Selassie I (qedamawi Haile Selassie) meaning the (first power of the Trinity) name given to Ras Tafari upon his baptism and later assumed as part of his regnal name at his November 2, 1930 coronation by the Ethiopian Orthodox Tewahedo Church, then known as just the Ethiopian Tewahedo Church.
