Please let me give you some advice. Recordings are made by educational companies - get one of these.
Reason: One parent did not like a teacher's choice of music, used for the same purpose you are thinking of. Parent was really out to get said teacher. Union had to get involved, etc. The teacher was told by the school lawyer that SHE SHOULD HAVE PURCHASED THE CD FROM AN EDUCATIONAL COMPANY. This way, the parent could have issue with the educational company, not the teacher. Please be careful.
A word to the wise.......
