Do you know of any easy to use, freepascal compatible library for XM/IT/MOD playback (s3m isn't required as it is unpopular format - the only s3m songs I've seen are original Jazz Jackrabbit's soundtrack) that doesn't have license shenanigans that BASS and FMOD has (so you can sell games made using it without paying license fees)?

It should have easy api, like one BASS has (I'm familiar only with this library for module playback so it is my only point of comparison), so libmodplug is out of question.
