Tuning in seventies style generally took three forms, the portable radio, something with with it built in such as a radiogram or music centre or a seperate unit you attached to a Hifi of which is is one Tandy aka Radio Shack sold that did just what you needed.
It had VHF stereo for which a red coloured indicator came on if you tuned in a stereo station and Medium Wave (marked as AM) which had stations that weren't otherwise available although they didn't sound too good like Radio 1 for Pop Music.
Today there are different ways of "tuning" in such as internet radio stations, podcasts and streaming which is quite popular.
Streaming allows people to hear individual pieces of music or whole collections stored on line that you curate either for free with adverts and some restrictions of for a monthly or yearly subscription which in some ways is a virtual record or cd library when we paid so much for a weekly loan in the past and potentially the quality can be better.
Recently there has been some noise that a big player Spotify has improved the quality of its premium offer to something that potentially a bit better than standard cd but not as high as some specialist companies.
If your market is mainly people on the go, things like a persons data allowance comes into play on mobile phone contracts and in any event this tends to eat more battery current when the background may not that quiet.
All reproduce has compromises and perhaps this works best for their target audience rather than audiophiles with very quiet often treated rooms and very fast home fibre internet?
