In the battle of streaming music services, the number of songs is a key selling point. Does it really matter if one service has a million songs and another service has ten million songs? There are two ways that most people listen to music. They either want to hear a particular song (or songs) or they want to listen a random selection of songs, radio style. In either case, familiarity is more important than quantity. The service that has the most songs seems to be filled with crap and things I’ve never heard of. This causes me to skip a lot songs. That’s definitely a negative to how many songs they have licensed. Using these platforms as a discovery tool is an entirely different activity than listening to music, which again does not succeed based on how many songs are available.
