Hey, any site that adds video pics to YouTube MP3s? Quick for making playlists?

Going on a hike, I wanted upbeat YouTube music to keep me pumped. Looked for a tool that’s simple and doesn’t spam you. Discovered YouTube downloader service, and it’s crazy easy. Paste the link, grab your MP3, no drama. Seriously, the sound’s perfect and it’s free. My hikes are so fun with those tracks now!
