Available songs not appearing in searches

[JDubYew]

I've recently updated to Premium and found that certain songs which are available on the Spotify library just aren't showing up in my searches.
I've reinstalled the software since upgrading, but that hasn't fixed anything.
Gucci Mane - Lemonade is one example, and this is after following links from Google and links sent by friends via iMessage to the exact song. The links only take me to the album, but with the song I'm looking not present.
Any help would be greatly appreciated!
