Does anyone have a way to quickly download multiple songs at once so I don't have to bother with one at a time? I often make selections for trips, but most sites don't let me download many files at once. I need a convenient option where I can save a whole playlist at once. And so that it doesn't take too long.

I understand exactly what you mean. Downloading one song at a time is really inconvenient, especially if you are putting together a playlist for a trip. I found a great option for myself - https://tubidy.lc . This site allows you to download not only individual tracks, but also entire albums or collections, and without any extra steps or restrictions. Everything is downloaded quickly, and you can immediately get the entire playlist in the desired format and quality.
