The main page says that the site owner pays all royalties on an annual schedule. Donations are strictly voluntary and they won't nag you for donations.

Caveat: The quality of the songs is definitely 'lo-fi' but adequate for determining chord progression, key, tempo, etc.

I have used them in the past with success and the price is definitely right ( free ).

You can select a particular genre, artist, year as a custom playlist and have it play in the background while you continue to work on other chores. Great for reminiscing.

Just discovered - you can't skip the player sequence. What should we expect for FREE?

I will simply record them to my own playlist for greater control.
