WON’T UPLOAD ANY MUSIC – Learn That Song (REMIX Edition) — Slow down music, change the key, and loop [previously iLift] Review

Anytime I try to go upload a song from my music, the only thing it is bringing up are my downloaded podcasts...???... It doesn’t matter which tab I click (songs, albums, artists, playlists), it won’t show any music to choose from. I paid $5 for this app thinking it was an upgraded iLift... App Developed, please help.
