I'M ONLY REPOSTING BECAUSE IT WAS A INEXPERIENCED LOCK

Hi, my main music provider on my phone is Google Play Music, and I have a playlist of over 180+ (!) songs on there. But when my mother lets me buy a £1 song, I proceed to buy it, and when I search for it, BIGBADABOOMBUYORDOFREETRIAL shows up, and I press the back button, and I'm back to music homepage, but everything has now changed. I think my trial period is ending, and the app says something about subscripted music. Do I lose access to all my songs, just the bought songs or the 'subscripted' music I have no idea what it is?
