Streaming services have become popular for a variety of reasons. One of the main reasons is the convenience they offer. With streaming services like Spotify, Apple Music, and Tidal, users can access a vast library of music on demand and listen to it on multiple devices, including smartphones, tablets, and computers. This allows users to easily discover new music and create playlists without having to purchase individual songs or albums. 

Another reason for the popularity of streaming services is the affordability and flexibility they offer. Many streaming services offer a variety of subscription options, including free or low-cost plans, and allow users to cancel or change their subscription at any time. This makes it easy for users to try out a service and find the plan that best fits their needs and budget. 

The rise of the internet and mobile devices also contributed to the popularity of streaming services, as it makes it easier for people to access and listen to music wherever they are. 

Additionally, streaming services often offer a variety of other features, such as offline listening, personalized playlists, and exclusive content, that make them an attractive option for music fans. 

Lastly, streaming has become a crucial source of revenue for the music industry, many artist, record labels and music streaming providers offer exclusive content, behind the scenes footage and more, which is only available through streaming services. This helped the industry to counterbalance the decline of physical music sales. 

In summary, streaming services have become popular for their convenience, affordability, flexibility, and additional features, as well as the technological advancements, making it easier for people to access and discover music.
