If you can't find a song or album it could be due to the licensing agreements with the labels. Therefore, some times, content varies from region to region. Other times even, agreements can't be reached with the artist or label, or a change may happen in music ownership. If you can't find an artist/song you're looking for, they may appear (or reappear) soon.
In the meantime, feel free to contact the artist or their label to ask when they plan to be on Spotify.
Thank you for the reply. I'm aware of how it works, but the other albums by Hedley that are available are signed by the same label as the album that is not available which is why I'm a bit confused on why.
@xRecklessx Hey there! If you're writing from the US, Storms was never actually released down here. In Canada their albums have all been released by Universal Music Canada, but down here they've been released/distributed by different labels. It's a great album, so very frustrating, I know! :)
