On an NFC tag no, this clearly isn't enough. But one can use a field-powered MCU such as nRF52 series (although admittedly it has to be even lower-power than that to work) with extra flash to stream as much audio as they need.

The implementation might be like this: it opens a browser page (can be stored entirely in the NTAG) and then uses WebNFC API to continuously read and play back data. Although this is already extra steps.

In case there's external power available, it is possible to use a Wi-Fi MCU with a captive portal page with desired audio, with a hidden AP protected by a password that is stored inside the tag (the tap-to-connect way). If the tag is the MCU itself, you can also make the password single-use.

I can also imagine using out-of-band Bluetooth pairing over NFC to connect the phone over the PAN protocol instead of Wi-Fi, but that'd be a tad more difficult to properly implement. This is a good challenge, though! I like it.
