Motorola RAZR VE20

ok now i worked for months to figure out how to get ring tones and i have finally figured that out but some problems still allude me. so i bought a sd card the other day and i bluetoothed songs to my phone from my mac but the only song that actually went to the music player is collide by howie day and i dont know why or how it did and i dont know why or how my other songs arent. there is no obvious option to add them to the music player from what i can tell. so please help. also i have seen in reviews that a phone had different buttons for the three touchscreen options on the front how is this possible to change?
