Theresa,
If these songs are stored as regular music files (.mp3?) on your phone then you should be able to save them to the cloud (Google Drive; Dropbox; etc) or to an SD card or to your computer.
The first thing to do is to see if you can find where they were saved. If you don't remember where Music Paradise downloaded them, you can use the 'My Files' app to look for them. Assuming that you don't have an SD card in your phone, the My Files app will default to showing the internal memory (/storage/sdcard0).
You can look around to see if you can find a Music Paradise directory or just do a search for any music files:
- in the My Files app, press the Menu button and select 'Search'
- in the Search box enter ".mp3" (without the quotes; don't let it put a space between the period and the m) and select the search button in the lower right of the keyboard
- see if any of the results look like the music you're looking for; if so, make note of the directory that they're stored in
- exit the Search function and navigate to the directory that you made note of
Now that you know where the music is stored you can use any of the original options to copy them somewhere else. I can't explain how to use Google Drive and Dropbox and all the rest here, but I'm sure you can get help if you decide on one solution.
Note that Samsung provides software for your computer called Kies which will let you backup your contacts, call logs, SMS/MMS, pictures/videos/music and TouchWiz settings. Then you can restore that information to a replacement phone.
