Q. Can I play music from a streaming service such as Spotify or Google Play to my students?
Both Spotify’s and Google Play’s terms and conditions restrict use to “personal, non-commercial use", so it would ordinarily be a breach of the contractual terms to play music under any other circumstances, though not a breach of copyright law.
However, the recent (June 2014) changes to the copyright laws in relation to educational use mean that legal provisions override the contractual terms, if they forbid anything that is allowed under the law; therefore academic staff would be allowed to play such recordings to students.
Another method of giving students access to recorded music could be to ask them to find and listen to the music themselves – a large repertoire is available on YouTube (legally, due to the various agreements YouTube have with music publishers), for example.
