On Monday, the tech giant announced that it will be releasing a streaming service later this month.
Apple Music will combine music downloads, streaming radio and a streaming music service. It will cost $9.99 a month, or $14.00 for a family plan of up to six people, with a three-month free trial. The new music service will be available June 30, Apple says, and an Android version will be coming in the fall.
After Apple's announcement, Daniel Ek, CEO of Spotify, apparently responded with two little words: "Oh ok."
The tweet—which a Spotify spokesperson declined to comment on—was deleted shortly after, but not before Twitter users took note.
Rdio also addressed Apple's entrance to the streaming world:
"Welcome, Apple. Seriously. Welcome to the most exciting and important frontier since the digital music revolution began 16 years ago. We look forward to responsible competition in the massive effort to make music available legally for anyone to enjoy anytime, anywhere. Because what we are doing is increasing the value of music by enhancing each individual's experience with music they love. Welcome to the task."
The statement was mirrored after Apple's statement to IBM in 1981, after the announcement of its first PC.
Shares of Pandora ended Monday down nearly 4 percent, while Sirius dropped 1.8 percent. On that note, Apple also found itself in the red, closing down more than half a percent.
