well i usually go on Google and type the name of song and artist and then type mediafire and search. ou go on a website called abmp3 ou go on downloadnl and chercher it there. Totally free! I do it all the time when i'm on the internet on my phone.
I use mytinyphone.com It's not just for ringtones toi can look up Full songs and save it to your Pc aka your Computer but make sure the song is the full song becuz other people who put the songs there might say full but it's not so watch out for the Song's Duration time.
toi will need lim wire and media player .they're probally other ways to do it . but this way is actually easy.i i had the same problems your having.just actaully got mine to run last monthi've been having my mp3 since christmas,,,!lol.
