I have a Nokia 5610 Music Express ?

[~~BELLtLA~~]

I have a Nokia 5610 phone. I want to Download music to it. But I'm having trouble and have some questions. My first question is can you convert youtube videos and download them to the phone? Or can you download the music from youtube to the phone? If so whats the easiest way to do so. My other question is for those of you that have his phone, have you downloaded any music from any particular site (s) that seem to work well for this model and can be trusted ? I have tried to find a website that I can easily download straight to the phone but I am having trouble and I was hoping that someone out would be able to help.
Thank you in advance !
