Hi guys
I am indeed a beginning user of audacity. I feel pretty comfortable with the format, but I have a few questions maybe I could get help with.
I am aspiring to make music mashups. I have asked around in the Greater Chicago area from friends to dj’s and producers and everyone thinks I have great concepts. My question is though, how do I get the music onto audacity? Always says there is an error, so my guess is a drm conversion or an alternative format needs to be used.
Wondering if you guys can help, or know anyone who can
Thank you and have a good weekend

Audacity will recognize many audio format on its own (WAV, AIFF, MP3, etc). It will deal with a lot more if you install the FFMpeg software.

Note it’s different software if you have Audacity 2.3.0 and before than if you have Audacity 2.3.1 and later.

Scroll down to FFMpeg.
