ls FM radio even listenable any more?

Absolutely...
There is still great quality analog audio being broadcast.

I've had Yamaha, Mcintosh & Magnum Dynalab tuners.
I have an FT-101A & it sounds really good. I had been using a set of OK Audioquest IC's & when I switched to another brand reference quality cables, it sounded much better. When a good station playing a good quality song came on, it was shocking how good that tuner can sound.

My MD-102 arrived last night. It's got the upgraded audio section with big caps in it. It is a significant upgrade in sound quality. It's like putting on a MFSL LP.

I found myself listening to songs I have heard before, but it's a whole new listening experience. I listened to an entire Prince song since the sound quality was so good, and I can't usually make it through one of his songs...

I just heard a live song played on it & the sound quality is outstanding.
If you've given up on FM, you are missing out...

I am still into FM. But the fact is that almost all FM is digital, even though the signal itself is still analog. Radio stations play from HD drives, signal processing is sometimes digital and STLs - which many stations use - are frequently digital.

But you mention a special thing: live broadcasts. Although these are often also run through digital processing, there can be some real sonic gems in live broadcasts.

Not all FM is played from disks or digital files. The station I mentioned spins records if the DJ's have them.

Cleeds- 
Yeah, this one station says they ‘are loading up some vinyl’ but they may not be playing any...

I believe it depends on how much compression the fm station uses. The stations that use a lot of compression sound bad on a good system and the stations that use very little sound much better.
