Re:It’s Opus, it rocks and now it’s an audio codec standard

If you were using AAC (or anything else that's more advanced than MP3) a 3MB file would actually be listenable for a short song.
A 150MB FLAC file would be about 20-30 minutes long (based on a typical bitrate of 700-1000 kilobits per second).

Even mp3 works for "a short song", that's not the context of my comment though, its context is a 150MB FLAC file (~300MB bitstream) recompressed to 3MB with Opus.

A point I noted in my comment.
3MB will get you POTS-quality audio though. Lossless codecs usually compress audio to half the original size (so a 150MB FLAC file — for music — will correspond to ~300MB of raw bitstream). Lossy compression to something worth listening to will usually be around 10x compression, so ~30MB for an original 300MB bitstream.
A 35mn song compressed in 3MB probably won't be worth listening to.
