Music streaming, in plain words

An AI DJ is a streaming-app feature that picks the next song based on your taste, then introduces it in a synthetic voice — like a personal radio host.

BPM means beats per minute — a measure of song tempo. A typical pop song runs 100–130 BPM. Workout playlists target 130–150 BPM. Lullabies sit under 80.

Collaborative filtering is a recommendation technique that suggests songs you might like based on what similar listeners liked. Spotify's Discover Weekly is its most famous deployment.

Create a Mix is a feature in Trending Music that builds a personalized playlist for the moment you're in — pick where you are, how you're feeling, and the genre you want, and a fresh playlist generates in three taps.

A daylist is a continuously updating playlist that shifts throughout the day to match the listener's typical mood at that time — "liminal cottagecore tuesday morning" instead of "Pop Hits."

Lossless audio is digital audio compressed without throwing away any of the original signal — the file is smaller, but every bit is preserved. Most streaming uses lossy compression like AAC or MP3 instead.

Music discovery is the process of finding new songs and artists you didn't know you'd like — typically through algorithms, friend recommendations, music journalism, or radio.

Spatial audio is a multi-channel audio format that places sounds in three-dimensional space around the listener — front, back, above, below — using either Dolby Atmos or Apple's head-tracking implementation.

Synced lyrics are song lyrics that scroll line-by-line in time with the music, highlighting the active line as the song plays — like karaoke without the cover-version backing track.
