You can buy them off of iTunes, of that's what ur asking
if you go to lyrics.com,type in your song then look at the top or bottom and click send this song to your phone it will you just have to fill out some information 'bout your phone ( but its not for free )
You should have a filer on your phone where all the folders are . click on the folder where your music is and there sholud be a list of all your songs there click and hold a song to send then click the bluetooth option.
If you want to upload songs on your phone you need a cable that probably came with your phone you plug it into you phone and the other end in the computer then just upload music, but if your asking how to send music when you are sending a text message you click menu and add music pick a song then send it
Depends on the phone that you have. You can generally just plug your phone into your PC and drag your song onto your phone. If that doesn't work, I recommend using a cloud software such as Google Drive. Drop off the songs into your drive from your PC. Open it on your phone and download it.
