Wait for a few seconds and you should get {num_results} results back.\nIf spotify provides a preview for the song, when you tap the correct result you'll get a 30 second preview for the song, otherwise its just the name of the song. Once you pick the right result you'll get a button that says `Show links`. When you click on this it'll search GPM and Youtube for the song and will show the links.\n*This takes a bit, please be patient. If you wait more than 3 days, the button probably won't work. To fix that please search again.*")
