Cant get any songs

So I go on the original app to get my favorite song and then it told me to download an updated version, so I did. Then it told me I had to install another app to get my song, so I did. The app to download didnt even have my song when the other two did, so I tried a more popular song and on the downloading app there was only the Nightcore version.
