Believe it or not, upon moving to Memphis 4.5 years ago, I never opened up my laptop...I have mostly lived off my phone since...I realize it is time for me to get myself a PC going again so I can do stuff like this...I definitely used to do it...
Couple years ago, while waiting to get into a Sounders match, I was able to rip a video, convert it to MP3, trim it, and embed art. Mostly as proof of concept, partially so I could listen to the new Duran Duran single while I was waiting. The tools do exist.
/punchline: I did it all on a freakin' Windows phone, too
