Can I replace "from" to "to" here? Considering the meaning "to" seems more appropriate.
Great question. In this case, you cannot replace "from" with "to". We use the structure "request (something) from (someone)" to express a desire to obtain something from someone. This form is usually used when something specific is being requested, as is the case here, where he is being specifically asked to play a particular song. Ex: I requested a new passport from the embassy. Ex: He needs to request a different form from the company.
