Songs showing as grey on android but play on PC

[KelseyN]

I added a local file from itunes to my spotify library and the songs I added are on my spotify library on my computer and I can listen to them no problem.

In the past I've transfered songs from my PC spotify to my Android spotify this way with no problem. However these two songs I have on my PC won't teansfer to my android spotify, they show up as grey and I can't play them.

Any suggestions?
