Although as a reference in a general dictionary and not specialized in music it would be a bit forced, it is true that Reida is a theme of the musician Danheim; and since it is mentioned here, I add that - according to his admirers - it comes from the Old Norse Reið, which today means "angry", but in other times it was associated with thunder and the chariot of the god Tor or Thor. That is why 'reid' or 'reith' (as it is found more by influence of English) is the name of an ancient rune that in the current Gothic alphabet is called 'raida', is equivalent to our /R/ (erre) and is interpreted as "journey, horseback riding".
