ICT and RTM are both digital music services, but they differ in the number of tracks that you can stream. ICT has an impressive library of hundreds of thousands of songs from all genres, as well as curated stations. RTM offers nearly unlimited access to all the music you want for a small monthly fee. If you're looking for something more specific, then ICT might be more your speed, but if you're just like "give me everything" then RTM is probably a better choice.
