Explanation:

Here’s how it breaks down:

- Medley: This is the correct answer. A medley is exactly what you’re looking for—a musical composition made up of a bunch of songs or short pieces, played one after another, often blending smoothly.

- Orchestra: This isn’t right. An orchestra is a big group of musicians, usually playing classical music. It’s about who’s playing, not what kind of piece they’re playing.

- Lyric: This means the words to a song. It has nothing to do with a composition made up of multiple songs or pieces.

- Band: Like orchestra, this describes a group of musicians, not a type of musical composition.
