can you listen to unknown album songs?

[kingharmonia]

hey, i've found a song i like on youtube ("sleep thru ur alarms" by Lontalius) and i saw it on spotify when i searched for it but it was greyed out and said "unknown album". the rest of the songs from the same album i know its in are playable, but this one isn't? i did notice that with this song, "lontalius" is lowercase while its capital for the other songs, so was it maybe deleted or changed? anway is it just not possible to listen to songs with unknown albums, and furthermore why is this song labeled as such? thanks~
