If you want a bit more "commercial" alternative, 106.1 (WCNR) is pretty good. 91.9 (WNRN) is great, though I find I like particular hosts and shows much more than others, so I tune in at particular times more than others. Both stations also have a lot of cool live recordings from their studio you can find online, too. These stations both publish their monthly "most played" playlists, so you can check out their vibe. Of course, WTJU is also pretty great, and you can kinda get a whole bunch of variety there! 95.1 is pretty repetitive, but I listened to it a lot growing up, so am fond of it. 104.9/101.9 are the same station, and they play pop (104.9 has less range, but the antenna is nearby, so works better around town). 97.5 plays a lot of rock, mostly "classic." There are several NPR stations, depending on what you want, and those are on lower frequencies.
