Missing Music Service Features

The following is an evolving list of features that are missing from online music services.

Disclaimer: I am an old Rdio user and enjoyed how their experience was focused on discovering new music. Most of these features relate to discovering new music. However, there are some that improve the overall experience. I created this list after using Apple Music and most recently Google Play Music.

• New releases includes all albums released this week, only. This is a wonderful way to discover new artists that may be releasing their new LP, EP or single.
• New releases can be filtered to show last week releases and even the week before that.
• New releases is automatically sorted by play counts so popularity is driven by the community. This promotes non-mainstream artists to be discovered.
• New releases can also be sorted by music service recommendations. A recommendation can either be music service driven (e.g. "Google Play Music Featured Artist") or by the similar artist
