Spotify (SPOT) has more than doubled its stock price over the last year, and LikeFolio's Landon Swan says the music streamer still has room to run. While valuations are stretched, Landon says the price is justified due to its music streaming dominance through rapid audience growth. He adds that LikeFolio has Spotify as a "top ten holding" and sees a path similar to Netflix's (NFLX) in the TV and movie space.
